Main points
1. Plastics and microbeads that discharge to seas have deeply destroyed the marine system. It has caused starvation, suffocation, laceration, infection, reduced reproductive success and mortality of so many marine organisms.
2. Governments aware of the significance of plastics pollution and formulate laws and regulations to reduce the use of plastic products.These measures successfully reduced the increase in plastics pollution.
3. The plastics products ban are executed differently in different countries and areas. The developed countries do better than developing countries. Since 2002 many counties in the world have been running the plastics bag ban. But many developing countries can not completely avoid the use of bags in some small shops and street vendors.

Questions
1. If the bans on plastic bags and some other plastic products influent the economic growth in some developing countries?
2. Whether some wealthy developed countries should pay much more money and resources to curb marine pollution?
3. Is it an equal method for developing countries to follow the environmental governance that formulates by international groups?

1. I think this article brings us some new ideas on doing the research. In the article, the author pays more attention to the policies in reducing plastic pollution and try to measure its practical effectiveness. He makes the abstract problem more concrete by using quantitative methods, studying the data collected from the internationally coordinated monitoring campaigns. This method can connect to the knowledge we’ve learned in Research Methods in Business and Quantitative Skill for Business class at DUISC and can be applied to our later research. When we are going to make qualitative analysis to a problem, we can quantify it by measuring the various data to help us draw the final conclusion.

2. With the increasingly severe marine pollution, every country is attaching greater importance on the ocean environment protection. The policies of the ban on single-use plastics have been established in various countries and obtained great achievements. It can be expected that the marine pollution will be improved in the future. https://www.earthday.org/plasticban/

Sheldon:1,The article show us the adverse consequences to marine animals,but there are lack of exact examples .Hence, I find that some examples to show how the turtle can be stuck by the plastic and the impacts of plastic abuse.
https://www.newsweek.com/plastic-pollution-bigger-threat-sea-turtles-oil-spills-752585

2,The article concern the discharge of the microplastic and macro plastic to the sea.So people may not know about how long the plastic decompose and how it disappear? As I have search ,it takes up to 1000 years to decompose in landfills,but plastic bags we use in our everyday life take 10-1000 years to decompose, while plastic bottles can take 450 years or more.

Main Idea
1.Marine plastic pollution has caused extensive concern.Single used plastics like pastic bags and microbeads have serious impact on the marine environment.
2.Many governments and NGOs have taken corresponding measures to mitigate marine plastic pollution.Interventions to reduce the use of plastic bags have been varied in range and scope. But there have been limited interventions to reduce microbeads.
3.Consistent measures are needed to mitigate plastic bags and microbeads pollution. Also,strengthen related education will be effective on reduce marine plastic pollution.
Question
Q1:What's the plastic bags policy in your country?
Q2:How does charging for plastic bags affect people's consumption psychology and behavior?
Q3:Do you know why the pollution caused by plastic waste is permanent?
Q4:What's main difference between curb plastic bags pollution and microbeads pollution?
Q5:Which policy in the table(page20-21) is most effective?Why?

QUIZLET: https://quizlet.com/327181292/learn
I have created a quizlet which can help us learn the important terms more easily.

Marine plastic pollution - This subject specific concept is important for us to know because it has appeared 5 times in the article (including the abstract) and it is currently an alarming environmental issue for the members of the public world-wide. The overwhelming plastic pollution has caused devastating impact to the oceans and has become a major hazard to the marine ecosystem.

Single-use plastics: The article addresses and reviews the current plastic pollution reduction policies by focusing specifically on single-use plastics which are plastic bags and micro beads.

Aquatic ecosystem: An ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and fresh water ecosystems.
https://en.wikipedia.org/wiki/Aquatic_ecosystem.

Microplastics: National Oceanic and Atmospheric Administration (NOAA) define microplastics as fragments less than 5 mm in diameter, microplastics comprise: primary microplastics, and secondary microplastics, from degraded macroplastics (e.g., plastic bags).

Macroplastics: Macroplastics (larger than 5 mm) enter the marine
environment via dumping or poor waste management. Large pieces of plastic (macroplastics) can cause significant harm in the marine environment through entanglement.

Marine plastic debris: Also known as marine litter, is human-created waste that has deliberately or accidentally been released in a lake, sea, ocean, or waterway.

Speaking of plastic pollution, it really remind me of this show
https://www.youtube.com/watch?v=7W33HRc1A6c
It is from George Carlin.
And someone has translated it into Chinese, please check the website to help you to understand if needed.
http://blog.sina.com.cn/s/blog_7e7dd3120100ub70.html
Mainly ,the show says that protecting the Earth from plastic pollution is not necessary for Earth and it is actually for human.

I think the drawbacks of plastic pollution are quite clear and we have receive enough education about it, but we are still using plastic bags for convenience. Maybe it is because when we use the bags we do not immediately realise the drawbacks. And we could print picture on plastic bags just like cigarette cover, I believe more people would be willing to bring a bag when they go shopping.

1.This article of current international market-based strategies and policies to minimize single-use plastics provides important information and highlights gaps for decision and policymakers. However, many countries are still lack any implementation strategies. in addition, Education and outreach programs to modify behavior should be widely adopted.
2.Plastic bags have been identified, among microplastic litter items, most harmful to marine biota. The research is required to assess whether reductions in single-use plastic bags are maintained, and indeed, more research is required to determine whether these reductions are having a positive impact on aquatic or marine environments. The lack of global policy studies aimed at mitigating single-use plastics accumulating in the marine environment was the driver for this study.

The article introduces plastic pollution.
Firstly，the author tells us some sorts of plastic pollutions，and also shows the negative impacts caused by plastic pollution.Then the article shows some international strategies for resolving the problem.Variable policies have been used in many nations.But different countries have different policies and some countries still have problems in reducing pollution.Although plastic bags and microbeads have been banned or reduced in many nations，the amount of those plastic items is still huge.The author said that more effort should be put on to reduce the pollution.

Main point
1 Plastic pollution involve microplastics and macroplastics pollution. These pollution cause negative impacts is not only on marine species survive and environment sustainable but also on tourism and economy and it is gradually growing up to be a global issue.

2 .Through diversity of study governments all over the world have strategies to ban the sale of lightweight bags, charge customers for lightweight bagsand/orgenerate taxes from stores who sell them.

3 In practice to restrict plastic bag use is lack legislation support and implement strategy.

Question
1 Distinct the difference between two main plastic pollution source.

2 What is the damage cause by persistent plastic.

3 What is the damage cause by large plastic items

4 What did UK government did to prevent the plastic bag use.

Kirsty's Class-Jinbo

2018-10-14 00:58:03 UTC

MAIN IDEAS:
1)Plastics are widespread in the marine environment. Stranded plastic which makes adverse effects on economic development and human life influence animals' life.
2)Microplastics would finally enter the human food chain through eating seafood. And it affects people's health.
3)Some cosmetics contain microbeads which cannot be filtered by wastewater treatment facilities are released into the ocean. So it would cause environmental problems.
4)A lot of countries including developing and developed countries enact laws or charge for plastic bags compared with fewer nations implement policies to limit the use of microbeads.
5)The levy about single-use plastic bags in England had made a huge difference to reduce the consumption of them. And monitoring is a crucial way to ensure the strategies of plastics bag bans are being adhered to. Besides, Educating youth and other stakeholder is a valid way to raise the awareness of avoiding using plastic bags and cosmetics which contain microbeads.
QUESTION:
1)What impacts will microplastics cause when we release it into the sea?
2)Have any countries found something to replace the use of microbeads in cosmetics?
3)What is the outcome after the UK had levied to the single-use plastic bags?
4)What are the differences between microplastics and macroplastics?

2018-10-14 10:32:45 UTC

Main idea:
1.plastics and microbeads bring many impacts to not just the marine environment but also people's health. It attracted counties to pay attention to reducing the pollution on plastics and microbeads.
2. Governments all over the world took some action, like release bans or make strategies, to reduce the marine pollution of plastics and microbeads.
3. Different countries intervened the global microbead and plastics policy to reduce pollution and provide the evidence to prove the effectiveness of police.
Questions:
1. What the differences between microplastics and macroplastics? which of them will pose more of a threat to marine?
2.what impacts the microplastics caused to marine pollution?
3. What did the government and the NGOs do to reduce plastic marine debris?
4. How to evaluate the effectiveness of the policies?
5. what is the purpose of this article?

Gemma's class-YUE XI

2018-10-14 10:58:37 UTC

Main ideas

1. Plastics are now ubiquitous in the marine environment, and urgent action is required to mitigate this worsening trend.

2. The existence of plastics in the marine environment present a number of challenges that hinder economic development.

3. Economic losses are associated with reduced tourism revenus,negative impacts on recreational activities, vessel damage, impairment in marine environment, invasive species transport and damage to public health.

4. Recent studies suggest that risks of microplastics(including degraded macroplastics,microbeads and microplastic fibers in the marine environment may pose more of a threat that microplastics research and policies to reduce pollution from these source are lacking.

5. Even though 134 countries agreed to eliminate plastics disposal at sea, research has shown that the problem of marine debris has worsened since MARPOL 73/78 was signed.
This may be because the marine debris problem is related to incorrect disposal of waste on land.

6. While measures to reduce plastic bag pollution have long been established,many countries still lack any implementation strategies.

Questions:

1. What ICC suggest NGOs to do to mitigate marine debris?

2. What are the purpose of the two strategies come from Honolulu Strategy?

3. How many types of policies have been mentioned in this article?

4. Why in South Africa,the measure that to reduce the use of plastic bags is ineffective?

5. How to quantify the effectiveness of policies to reduce microbead pollution?

2018-10-14 13:04:37 UTC

Main Ideas:
1. The article draws our attention towards how plastic material can cause devastating effects on our ecosystem and the outcome of those results will lead to starvation, suffocation, infection, reduce re productivity and mortality.
2. It also explains about how micro plastics and macro plastic are distinguished and there effects on our environment.
3. Many laws and legislature came into order so the use of plastic bags as well as microbeads should be reduced.
4. Many government and non- government organization took affords to examine how the plastic waste should be deposed off in a safe way.

Questions:
1. What is the difference between Micro-Plastics and Macro-Plastics?
2.Which countries were in support of the ban of the plastic policy and what were there strategy?
3.What are the reasons due to which microbeads in cosmetic products were banned ?
4. Even though laws are in effects the problem of plastic pollution have not ended. What are the possible reasons ?

1.freshwater environments
Freshwater ecosystems are a subset of Earth'saquatic ecosystems. They include lakes andponds, rivers, streams, springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content.

2microplastics
Plastic is the most prevalent type of marine debris found in our ocean and Great Lakes. Plastic debris can come in all shapes and sizes, but those that are less than five millimeters in length (or about the size of a sesame seed) are called “microplastics.”

3 microbeads
Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension. They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene.

4plastic marine debris
Marine debris is defined as any persistent solid material that is manufactured or processed and directly or indirectly, intentionally or unintentionally, disposed of or abandoned into the marine environment or the Great Lakes.

5marine biota
Marine biota can be classified broadly into those organisms living in either the pelagic environment (plankton and nekton) or the benthic environment (benthos). Some organisms, however, are benthic in one stage of life and pelagic in another. Producers that synthesize organic molecules exist in both environments.

Main ideas：

1. Plastics are now seriously polluted the marine environment, and it not only has the negative influence on the marine organism but also will threaten human’s health.

2. Plastics include microplastics and macroplastics, and microplastics have more threats than macroplastics in the marine environment.

3. Both governments and non-government organizations are taking actions to reduce the plastic pollutions, but some countries still lack implementations or strategies.

Questions:

1. How plastics pollution threaten human’s health?

2. What are microbeads and how will they pollute the environment?

3. What does the government do to reduce the plastic bag pollution?

4. The plastics bag has great harm to human’s health, what’s the policy to deal with the pollution in your country?

5. How to comment on the different policy in different countries, are they effective?

1.mitigating single-use plastics accumulating in the marine environment

The main point has been study in this research is focus on the mitigating single-use plastics accumulating in the marine environment as the author claim there is lack of the studies focus on the related global policy. It also become the reason of the author to do the discussion session in three different parts.

2.NGO websites

NGO stands for non-governmental organization. In the methodology section, the author claim that there are not enough studies focus on this research question, which cause a knowledge gap for the author to build up with information not only from peer-reviewed articles and government websites ( resources normally be considered as reliable information), but also from certain NGO websites.

1. This article is talking about the how plastic pollution affect Marine. And this issue brings me back to our daily life. In my memory, when I was study in elementary school, the groceries store always provides free plastic bag for customer. And, I still remember that one day after shopping, the cashier asks me whether I need a plastic bag for grab my staff. It has been charging now. everything change after that. When I going to US for my undergraduate life, it even getting more control, some America local store only provide paper bag. And some even do not provide bag, the only bag they provide is Fabric. We can see those government strategies really pushing us to reduce plastic using. And it is getting better every day.
2.I saw a video from the BBC last month. It is taking about Mosquito plastic pollution. Mosquito grow up in the water surface until it becomes mature, and in these periods, they absorb the microplastic into their body. And because of it contain those in their body. The animal food chain will be affected by it, as well as our human. This news has shocked me, because of that what we hurt our environment is finally would hurt us, and it comes such a directly way.

1.The ocean pollution reminds me a shocking news I saw last year, a giant wheel died on the beach, experts dissect its body, found many plastic bags around its lung. Animals can not recognize the food from waste. Thousands of animals died because of eating plastic goods. Every time I heard such kind of news, I felt tearful and it grieved me for a long time. Its our fault to make them loose their lives. Related laws should be enacted by the government to highlight our awareness of protecting the marine animals.
https://www.bbc.co.uk/news/world-asia-44344468
2. Oil is the fastest source of deterioration to the ocean, being far more harmful than trash and waste. However, only a small percentage of oil (around 12%) dumped in the ocean comes as a result of actual oil spills. Most oil causing harm in the ocean is a result of drainage from land. Oil spills suffocate marine life to death, and leads to behavioral changes and a breakdown in thermal insulation to those that do survive. It essentially changes the entire ecosystem of an affected area.

1.Marine pollution
Marine pollution usually means that humans have changed the original state of the ocean and destroyed the marine ecosystem. Pollution caused by harmful substances entering the marine environment can damage biological resources, endanger human health, hinder fishing and other human activities at sea, and damage seawater quality and environmental quality. The characteristics of marine pollution are that there are many sources of pollution, strong persistence, wide spread and difficult to control.
2.plastic limit order
On December 31, 2007, the General Office of the State Council of the People's Republic of China issued the “Notice of the General Office of the State Council on Restricting the Production and Sale of Plastic Shopping Bags.” This notice, known as the “plastic limit order” by the masses, clearly states: “From 2008 From June 1st, it is forbidden to produce, sell and use plastic shopping bags with thickness less than 0.025mm nationwide; "Since June 1, 2008, in all supermarkets, shopping malls, bazaars and other retail outlets Plastic shopping bags shall not be provided free of charge if the system of paid use of plastic shopping bags is implemented. According to the document, in terms of environmental protection, plastic bags must be marked with the words “To protect the environment and save resources, please use it multiple times”. At the same time, the plastic bag should clearly identify the manufacturer's name and clearly identify the nominal load bearing in kilograms.

Plastics is ubiquitous in the marine environment. The essay said the contemporary social pollution issues ,how to solve them and show some methods to mitigate this condition. Tell the truth, we can see the plastics everywhere, it’s just like air in our daily life. For instance, we will buy the products in the supermarkets and hypermarkets, so it’s convenient to take items away with bags, which means people can carry them in a easy and quick approach.

Absolutely, people have learned how severe that pollution in marine. When I was a child and studied at the primary school, I heard that Antarctic bear will have no places to live, because human being just discharge waste into the ocean to let ice melt quickly than before. In my opinion, people just consider oceans as rubbish station, they put everything in it without see the result.

With the pollution become exacerbation, many countries implement different legislation to solve this question, putting bans, levies and so on. The important is that improve the education which is the positive impacts of these measures in the short-and long -term.

From a vast variety of complex vocabulary which pervades this article I have chosen some of the words which are recurrent and crucial to the understanding of the thesis:
1. Marine debris is defined as any persistent solid material that is manufactured or processed and directly or indirectly, intentionally or unintentionally, disposed of or abandoned into the marine environment or the Great Lakes.
2. Macroplastic - relatively large particles of plastic found especially in the marine environment (typically more than about 5 mm)
3. Microplastic - small barely visible pieces of plastic that enter and pollute the environment. To clarify, microplastics are not a specific kind, but rather is any type of plastic fragment that is less than five millimeters in length according to the U.S. National Oceanic and Atmospheric Administration (NOAA).
4. Microbeads are manufactured solid plastic particles of less than one millimetre in their largest dimension. They are used in exfoliating personal care products, toothpastes and in biomedical and health-science research.
5. Gyres - large systems of circulating ocean currents, kind of like slow-moving whirlpools. There are five gyres to be exact—the North Atlantic Gyre, the South Atlantic Gyre, the North Pacific Gyre, the South Pacific Gyre, and the Indian Ocean Gyre—that have a significant impact on the ocean. The big five help drive the so-called oceanic conveyor belt that helps circulate ocean waters around the globe. While they circulate ocean waters, they’re also drawing in the pollution that we release in coastal areas, known as marine debris.
6. Degradable - capable of being decomposed chemically orbiologically.

It is a regardless phenomenon in nowadays society that plastic pollution has definitely influenced our daily life.Not only can we see the plastic bags floating in the air , but also the plastic products have occupied a large amount of our daily used tools. It is seemed like not a big deal ,but we can see in the passage, 40 percent of the world, especially the wealthy countries, have involved in the harmful influenced of plastic pollution. Moreover, because of the effect of plastic pollution , the fine place for creatures living have reduced 10% in past 10 years.
https://www.bbc.co.uk/iplayer/episode/p069v922/arctic-plastic-pollution

To stop the disaster, author suggest to build up connections between governments, in my personal point of view, for individually, we can reduce the usage of plastic bags , carrying the bags to supermarket which have been used before. Everyone do a little, it is a large step for the world.

Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension. They are most frequently made of polyethylene but can be of other petrochemical plastics such as polypropylene and polystyrene

2. Ghost net
Ghost nets are fishing nets that have been left or lost in the ocean by fishermen. These nets, often nearly invisible in the dim light, can be left tangled on a rocky reef or drifting in the open sea. They can entangle fish, dolphins, sea turtles, sharks, dugongs, crocodiles, seabirds, crabs, and other creatures, including the occasional human diver. Acting as designed, the nets restrict movement, causing starvation, laceration and infection, and suffocation in those that need to return to the surface to breathe.

Main idea:

• Single-use plastics are a significant source of marine plastics pollution, and there are many evidences that they are seriously harming the marine environment and also causing human health problems.

• Governments and international organisations have struggled a very long time in reducing marine plastics debris, there are various range and scope of strategies implemented by different countries.

• Examine the effectiveness of various policies implemented by different countries, some country did reducing the plastics pollution effectively like UK. However, there are few studies found out that the policies have been inconsistently implemented in some countries like North America.

• Education and outreach programs are important, not only can they modify behavior of children, it also has social influence on their peers, parents and the community.

Questions:

1. How the microbeads and microplastics can affect the marine environment?

2. What are the strategies implemented to reduce the use of plastic bags by different countries?

3. What are the international strategies to reduce plastics marine debris?

4. Were the policies to reduce single-use plastics effective in UK?

Interventions to reduce the use of plastic bags have been varied in range and scope, lightweight bags are prohibited, there are several strategies like charging customers for lightweight bags and imposing taxes on stores. Bans, partial bans, and fees have been enact by more and more countries and municipalities.

https://www.theguardian.com/australia-news/2017/sep/06/queensland-bans-single-use-plastic-bags-from-july-2018

The author thinks policy tools is not enough, one of the best strategies reported to mitigate plastic pollution would be to reduce its consumption at source. And the author also suggests that education, outreach as well as awareness should be conducted. And now, students will learn how important it is to protect the environment both at home and at school, studying some basic knowledge and do volunteer work to collect plastic bags thrown away by other people.

1. Marine plastic pollution has become a significant environmental concern. Single-use plastics are a main source of this pollution. Large plastic items such as discarded fishing rope and nets can entanglement of invertebrates, birds, mammals and turtles. Besides, Microplastics can enter the human food chain through ingestion of fish, shellfish and filter feeders, causing potential human health impacts.

2. ICC encourages other NGOs and volunteer group to engage in mitigating marine debris by cleaning up coastal areas across the globe. In addition, the Honolulu Strategy have two focus. Onefocus on market-based instruments like levies on plastic bags. Second focus is create policies, regulations, and legislation to reduce marine debris like imposing bans on microbeads.

3. The research examine the effectiveness of various policies implemented by different countries, some country did reducing the plastics pollution effectively. Nevertheless, there are few studies found out that the policies have been inconsistently implemented in some countries.

4. Education campaigns will likely help to further reduce plastic pollution caused by microbeads and plastic bags at source. The reason is that education and behavioural change of children is crucial as they represent an important source of social influence among their peers, parents and community. Targeting youth and other stakeholders (e.g., citizens, governments, industry and NGOs) is an effective way to promote positive change and help increase awareness.

1. Microplastics

Microplastics are defined as all forms of plastics less than 5mm. They can enter the oceans as:
a) Primary microplastics such as beads from personal care products, microfibres from clothes and pre-production pellets (nurdles/mermaid tears).
b) Secondary microplastics which are derived from larger plastic items which slowly get broken into smaller pieces.

2. Macroplastics

fragments >5 mm, which enter the marine environment via dumping or poor waste management

3. Single-use plastics

Single-use plastics, or disposable plastics, are used only once before they are thrown away or recycled. These items are things like plastic bags, straws, coffee stirrers, soda and water bottles and most food packaging.

4. Marine plastic debris

is human-created waste plastic that has deliberately or accidentally been released in a lake, sea, ocean, or waterway. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack.

5. Opaque

preventing light from travelling through, and therefore not transparent or translucent:

microbeads:

used in hundreds of personal care products like skin exfoliants and soap, can slip through water treatment systems and then become part of the plastic pollution of the oceans.

macroplastic :

Relatively large particles of plastic found especially in the marine environment (typically more than about 5 mm)

microplastic:

Small particles of plastic found especially in the marine environment (typically less than about 5 mm)

gyre:

【specialized】 a circular pattern of ocean currents (= flows of water in a particular direction)

e.g.The area is one of the world’s five major ocean gyres – huge systems of rotating currents.

【literary】 a circular movement in which each circle is above, below, or wider than the one before

e.g.The hawk wheels in a widening gyre.

single-use:

used to describe a product that is designed to be used once only

e.g.Sales of single-use cameras fell by 2% last year.

debris:

broken or torn pieces of something larger

e.g.Debris from the aircraft was scattered over a large area.

exacerbate:

to make something that is already bad even worse

e.g.This attack will exacerbate the already tense relations between the two communities.

1.Marine pollution occurs when harmful, or potentially harmful, effects result from the entry into the ocean of chemicals, particles, industrial, agricultural, and residential waste, noise, or the spread of invasive organisms. Eighty percent of marine pollution comes from land. Air pollution is also a contributing factor by carrying off pesticides or dirt into the ocean. Land and air pollution have proven to be harmful to marine life and its habitats.^[1]

The pollution often comes from nonpoint sources such as agricultural runoff, wind-blown debris, and dust. Nutrient pollution, a form of water pollution, refers to contamination by excessive inputs of nutrients. It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrates or phosphates, stimulate algae growth. Many potentially toxic chemicals adhere to tiny particles which are then taken up by plankton and benthic animals, most of which are either deposit feeders or filter feeders. In this way, the toxins are concentrated upward within ocean food chains. Many particles combine chemically in a manner highly depletive of oxygen, causing estuaries to become anoxic.

When pesticides are incorporated into the marine ecosystem, they quickly become absorbed into marine food webs. Once in the food webs, these pesticides can cause mutations, as well as diseases, which can be harmful to humans as well as the entire food web. Toxic metals can also be introduced into marine food webs. These can cause a change to tissue matter, biochemistry, behaviour, reproduction, and suppress growth in marine life. Also, many animal feeds have a high fish meal or fish hydrolysate content. In this way, marine toxins can be transferred to land animals, and appear later in meat and dairy products.

In order to protect the ocean from marine pollution, policies have been developed internationally. There are different ways for the ocean to get polluted, therefore there have been multiple laws, policies, and treaties put into place throughout history.

2.Plastic pollution is ubiquitous in the ocean but causes the most serious harm near coastlines and during its journey towards open waters. Existing in a variety of shapes and sizes, plastic litter harms marine life and incurs a cost on coastal economies. • We know enough about the damage done by oceanic plastic pollution to act now. However, solutions require concerted action by a range of stakeholders. The most promising solutions include: – Managing plastic waste at source, for instance by raising awareness amongst the public of the harm caused by plastic pollution as well as the economic and intrinsic value of plastic materials.
– Developing and expanding the use of plastics that truly degrade in the ocean.
– Managing waste and litter streams better: eliminating unnecessary products, ensuring adequate waste management systems are in place, setting up a circular economy for plastic products and waste where possible, boosting recycling, and incinerating unrecyclable plastic waste for energy in conjunction with the development of carbon capture and storage technology to balance the trade-off with greenhouse gas emissions.
– Using alternative materials to plastic where possible, such as substituting the microbeads in the cosmetics for non plastic alternatives.
– Cleaning up existing plastic pollution, with a focus on waterways, sewerage plants and coastlines.

1. Piece of plastic is dangerous for marine life. Fish or marine organisms cannot digest particles and microplastics. Ecosystem and food chain can be damaged and it is potentially harmful to humans. There are plastic on the beach not only from bottles but also from clothes. Many researches have been done and students focus on marine problems.
https://www.theguardian.com/developing-sustainable-solutions-university-of-plymouth/2018/oct/01/sea-change-fighting-for-the-future-of-our-oceans

2. This journal is about plastic problems on the beach. It reminds me of my experience. I use facial scrub once or twice a week. When I buy facial scrub, I usually choose one with microbeads. It seems to me that facial scrub with microbeads clean my face better than others without microbeads. I read news article one year ago. I found that microbeads do not dissolve in water and it could affect ecosystem. I do not buy facial scrub with microbeads.

Mann points:
1 Single-use plastics are a significant source of marine plastics pollution, It attracted many counties to pay attention to reduce using of pollution on plastics and microbeads
2 Governments are fully conscious of the significance of plastics pollution and enact laws and regulations to reduce and restrict the use of plastic products，. These measures had reduced plastics pollution.
3 some countries reduced plastics pollution effectively like UK. However, there are few studies found out that the policies have been iimplemented in some countries like North America.
4 Governments which from all over the world try to ban the sale of lightweight bags by charging customers for lightweight bags and/or generate taxes from stores.
Question
1,why it’s not every country in the world ban single -use products?
2Do you think it’s necessary for government to deal with plastic pollution by law?

1.The typhoon "mangosteen" caused the seawater to be poured. When the seawater retreated, the road surface was covered with foam and other marine debris, which were so devastated. The garbage that was originally thrown by humans was returned to them after a typhoon. On October 13, the first International Children's Ocean Festival and Shenzhen International Ocean Clean Day were held. There are more than 30 sub-meeting venues in the Jinshawan Seaside Resort and the Shenzhen Coastal Yacht Marina. More than 3,300 kilograms of garbage were cleaned on the same day. Activities from the beach, the sea, the seabed, the coastline, four directions, comprehensive marine cleaning. More than 50 scuba diving and free-skiing frogmen from Guangdong, Hong Kong and Macau and overseas have gone to the sea to clean the rubbish.

Andrew Turton and Pete Ceglinski, two avid surfers, decided to quit their jobs to create a “Seabin” that would collect trash, oil, fuel and detergents.

The mission of this project is “HAVE POLLUTION FREE OCEANS FOR OUR FUTURE GENERATIONS”.

The Seabin is a floating rubbish bin that is located in the water at marinas, docks, yacht clubs and commercial ports. The Seabin moves up and down with the range of tide collecting all floating rubbish. ... The Seabin also has the potential to collect a percentage of oils and pollutants floating on the water surface.

Main Idea:
• Single-used plastics, such as plastic bags and microbeads cause a severe damage to marine environment.

• Governments around the world implement bans and levies to prevent plastic bags from buying in store, and also to prohibit using microbeads in cosmetics.

• There’s a gap between research and implement, however this gap can make the monitoring system more completed.

• UK government put information into children’s education, in order to change the concepts between plastic litter and marine environment.
Questions:

1. How microplastics affect the marine environment?

2. What strategies did the government use to decrease the use of plastic bags? Please find the examples from any countries which has been mentioned in the article.

3. What did UK governments do to deal with the microbeads problems in 2016?
4. What method can ensure that the interventions are being complied with due to lack of information on banning microbeads? Please find an example in the article of how it works.

2.This article reviews current international market-based strategies and policies
to minimize single-use plastics (plastic bags and microbeads) provides important information and highlights gaps for decision and policy makers. While measures to reduce plastic bag pollution have long been established, many countries still lack any implementation strategies.
3. Internationally, all interventions to reduce single-use plastics vary in range and scope. Policies have been developed across a number of nations to ban primarily the use and sale of, but also the manufacturing of microbeads. Measures to reduce plastic bag pollution have included bans (including both full and partial) and levies, and these interventions have occurred both regionally and nationally. Although reduction strategies provide tools to reduce single-use plastics at source, it is recommended that consistent measures continue to be implemented to mitigate plastic bag and microbeads pollution. However, it is equally important that research measure the positive impacts of these measures in the short- and long-term. Education campaigns will likely help to further reduce plastic pollution caused by microbeads and plastic bags at source.

This paper reviews current international market-based strategies and policies to reduce plastic bags and microbeads

From this website, we can know that we are turning our beautiful Ocean into a plastic soup. About 8 million tonnes of plastic enters the sea every year, and at this rate we face a future with more plastic in the Ocean than fish by 2050. Our plastic addiction and waste mismanagement is condemning countless marine birds and animals to death by entanglement or poisoning, and even leading to chemical contamination of the fish we eat.

Main idea:
1. Plastic products like plastic bags and microbeads are putting a big threat to marine system, which is harmful for marine organism and human health.
2. Governments around the world started to enact some strategies to reduce marine plastic debris, but they were struggled at first, such as the MARPOL in 1973.
3. The methodology they used is mainly aimed to mitigate single-use plastic products and microbeads, the main cases are ban or levies plastic bags and limited interventions to reduce the use of microbeads.
4. Results of these methodology are good, especially the limitation of plastic bags, many countries' number of plastic bags using was sharply decreased.
5. The against of plastic products has worked and succeeded, but we still have to work harder to protect marine system and organism, and education about this is more and more important.
Questions:
1. Marine pollution and stopping using plastic products, which one exert a worse impact on human beings?
2. What should we do to reduce the use of microbeads in spite of it cannot be replace for now?
3. What is the potential impact of marine pollution for next generations?
4. Governments has made some incorrect strategies at first, why?
5. If we finally find a material which can completely replace plastic, can we solve the problem of marine pollution as well?

Main point:

1. Marine plastic pollution is mostly caused by single-use plastics (plastic bags and microbeads). It has a negative influence on marine life and economic development.

2. Many countries are concentrating on solving the problems of marine plastic pollution for decades. Their governments have made many regulations to restrict the use of plastic products. To some extent these solutions reduce the marine plastic pollution.

3. In addition to resolving the problems of pollution directly, governments can also pay more attention to education.

Questions:

1. What may be affected by marine plastic pollution except marine life and economic development?

2. Compared to plastic bags, why do governments have limited interventions to reduce microbeads?

3. Why will education campaigns have a further reduction in plastic pollution?

4. How to evaluate the effectiveness of the policies?

• Using Single-use plastics (plastic bags and microbeads) is one of the causes of marine plastic pollution. This is not only an environmental problem, but also an obstruction to economic development and harms human health. Therefore, efforts are needed to reduce using single-use plastics.
• Plastic is divided into Microplastic and Macroplastic. Both have a great effect on marine pollution. Plastic bags are representative example of macroplastics. Microplastics are very small size and also can be found in cosmetics. While there are currently many policies associated with reducing macroplastics, microplastics-related research or policies are insufficient.
• Plastic bag policies usually take a national approach and implements market-based strategies. Most countries tax plastic bags and even ban the sale of them. Each country has different standards on plastic bags and different policy detail.
• There are few policies related to microplastic and also their effects are uncertain. Some countries enforced their own policies, but some still have no policies to do with them.
• Policies for marine environmental preservation should be prepared and maintained for a long time. Moreover, monitoring studies assist to check the maintenance or these policies. There should also be more macroplastics-related policies created and more studies should be done on the marine pollution impact. Education campaigns and awareness about marine pollution are also significant, and most importantly, reducing its consumption at source.

1. What is the different between microplastics and macroplastics?

2. What are the two things that The Honolulu Strategy focused on?

3. What are the criteria for levying a plastic bag?

4. Why can’t many countries implement policies regarding microbeads right away?

5. Why is the monitoring about policies necessary (e.g. South America)?

6. What are the methods suggested by the authors of this study other than policy making?

A small explosion on 12 March, or caused by a hydrogen explosion. People in the industry say the fukushima plant is a technically now unused single-storey circulating boiling water reactor, with cooling water introduced directly into seawater, and there is little hope of safety. An evaporative substance produced by boiling water. For Japan, a quake-prone region, the use of such structures is highly unreasonable. An explosion occurred after the March 14 earthquake. After the explosion, radioactive material was blown into the wind, which spread to the Chinese mainland, Taiwan, Russia and other regions.

1. Q: Entanglement of species by marine debris can cause？

A: It can cause starvation, suffocation, laceration, infection, reduced reproductive success and mortality.

2. Q: What’s the growing concern related to microplastic effecting on human and what do studies found?

A: The microplastic can also enter the human food chain through ingestion of fish, shellfish and filter feeders, cause potential human health impact. Filter-feeding mussels have been reported to contain microplastics in their tissues.

3. Q: How about the interventions for plastic bags in North America?

A: Only two cities and six municipalities have imposed levies or bans on plastics bags in Canada.

Only four states have imposed bans or levies on plastics bags in the U.S.

4. Q: What’s UK government plans to do in 2016 and by what means it was successes

A: In 2016, UK gov announced plans to ban microbeads in cosmetics and personal care products by the end of 2017. The ban followed the successful introduction of the five pence plastics bag charge.

5. Q: What’s manufacturers across UK doing to release the environment pollution cause by plastic.

A: They are exploring natural alternative, including nut shells, salt and sugar, which have exfoliating properties but do not pose threats to the environment.

Microbeads: very small pieces of plastic that are added to products for cleaning the skin

Eg: (Abstract) Recommendations to further reduce single-use plastic marine pollution include: (i) research to evaluate effectiveness of bans and levies to ensure policies are having positive impacts on marine environments; and (ii) education and outreach to reduce consumption of plastic bags and microbeads at source.

Microplastics: small plastic pieces less than five millimeters long which can be harmful to our ocean and aquatic life

Macroplastics: clearly visible plastic that can be caught, to say it in an easy way, and will not (with a few exceptions) have a direct impact on the food chain

Marine debris: also known as marine litter, is human-created waste that has deliberately or accidentally been released in a lake, sea, ocean, or waterway

Ubiquitous: seeming to be everywhere

Eg: (Introduction) Plastics are now ubiquitous in the marine environment, and urgent action is required to mitigate this worsening trend (Rios et al., 2007, Rochman et al., 2015b).

Entanglement: a situation or relationship that you are involved in and that is difficult to escaped from

Suffocation: death caused by not having enough oxygen, or the act of killing someone by not allowing them to have enough oxygen

Laceration: a cut (in your skin)

Eg: Entanglement of species by marine debris can cause starvation, suffocation, laceration, infection, reduced reproductive success and mortality (Katsanevakis, 2008, Baulch and Perry, 2014, UNEP and NOAA, 2015).

Exacerbate: to make something that is already bad even worse

Eg: Accumulation in these gyres is exacerbated because plastics take centuries to degrade (Cole et al., 2011).

Aquatic: living or growing in, happening in, or connected with water

Eg: However, wastewater treatment facilities are not designed to remove manufactured microplastic particles, which means that these are currently released into aquatic ecosystems.

1. How does at least one of the ideas in the text connect to your modules at either DUISC or a previous course you have studied?

There is an article we studied in the AES class referring to water pollution, which is similar to plastic pollution, and the title of this article is “Meeting China’s Water Shortage Crisis: Current Practices and Challenges”, written by Hefa Cheng, Yuanan Hu and Jianfu Zhao, published in Environmental Science and Technology.

2. How does at least one idea of the text connect to a past or current news story or a historical event?

There was a news about excess garbage, recycling and organics in Canada a few years ago, prescribing the solutions of excess garbage, recycling and organics, including plastics stuffs.

https://www.toronto.ca/services-payments/recycling-organics-garbage/houses/excess-garbage-recycling-organics/

3. How does at least one idea of the text remind you of a personal experience you have had?

From 2008, China has passed legislation to ban free plastic bags sold by shops, supermarkets and sales outlets. Indeed, it is useful to reduce the amount of plastic bags because loads of families choose cotton bags instead of plastic bags after that, which is non-single-use and much more economic than buying plastic bags every single times.

1. Apart from viewing news and reports about ocean pollution, I have seldom learnt some ideas about it from the class. But this phenomenon do reflect a problem, that is the loss of education in reducing ocean plastic pollution. Majority of people from my nation are live in areas far away from ocean, so without social media, it is hard for especially students to realize the severe situation, they would still buy lots of toys made from microplastic, eat junk food wrapped with plastic bags and are even always fond of using toothpaste with bling small particles. But if they were educated knowledges about the danger of plastic pollution and measure to reduce those, the awareness of ocean protection would be established from the root of human beings.
2.Recently, researchers found that about half of baby turtles’ stomach were full of plastic. Also, by studying plastic stuffs in big turtles’ stomach, they found some of it were remained in turtles’ body for years, which is extremely hazardous for their digestive system.Because of plastic pollution, the amount of turtle is drastically decreasing.
3.I remember when I was preparing IElTS, there were several articles listening materials concerning the damage caused by plastic pollution. Especially for marine species, like whales and dolphins. Recently, there are always plenty of whales or dolphins stranding and dead on the coastline, researchers found environment pollution play a role in this phenomenon. Because many whales and dolphins’ sensation system was damaged by ingesting loads of chemical particles like microbeads and eventually their damaged sensation system mislead their direction and cause they stranding.

1.Ubiquitous

If you describe something or someone as ubiquitous, you mean that they seem to be everywhere.(omnipresent)

2.Single-use plastics

The article addresses and reviews the current plastic pollution reduction policies by focusing specifically on single-use plastics which are plastic bags and micro beads.

3.microplastics
Plastic is the most prevalent type of marine debris found in our ocean and Great Lakes. Plastic debris can come in all shapes and sizes, but those that are less than five millimeters in length (or about the size of a sesame seed) are called
“microplastics.”

4.Macroplastics

Relatively large particles of plastic found especially in the marine environment.

5.Suffocation

Death caused by not having enough oxygen, or the act of killing someone by not allowing them to have enough oxygen.

6.Microbeads

They are manufactured solid plastic particles of less than one millimetre in their largest dimension. They are used in exfoliating personal care products, toothpastes and in biomedical and health-science research.

1.Plastics have caused great pollution to the marine environment. Therefore, measures to alleviate this situation are imperative. However, the policy is only a countermeasure against the global plastic problem, and the real solution to the problem at the source is to enhance the education of the younger generation, so that they will pay enough attention to the problem of marine plastic pollution, and also raise the awareness of the community about the pollution of marine plastics. These are ways in which pollution can be improved in the long term.
2.This article reminds me of the

Amorgos oil spill.On 14 January 2001, the Greek merchant vessel Amorgos, lost power while en route from India to North China.^[1] The carrier was transporting approximately 60,000 tons of iron ore and an estimated 1,000 to 1,150^[2] tons of fuel oil when the ship suffered engine failure near Kenting National Park, off the southernmost tip of Taiwan.
Approximately 1,300 tons of fuel oil leaked from the Amorgos into the sea surrounding Kenting National Park, causing major damage to the maritime and local environment.^[3]Kenting National Park is an ecological attraction that draws millions of tourists each year due to its warm climate and its many natural phenomena, including limestone caves, monsoonforests and coastal rainforests.^[4]Around 4 to 5 kilometers of the Kenting National Park shoreline was oiled by the spillage, creating a hazardous environment for the 200 bird species and estimated 2,200 plant species within the park.^[5] Park officials reported that contaminated coral and dead fish, crabs, shrimp, and clams have washed ashore.^[2]^{https://www.sciencedirect.com/science/article/pii/S0025326X05001116}

1. Which countries tried to ban plastic bags and which tax plastic bags?

A: Bans, partial bans, and fees have been enacted by some local jurisdictions in North America, Australia, and the United Kingdom. Some countries in Europe where interventions are widespread, impose a fee per bag. Germany and Denmark were early adopters of plastic bag bans in most retail stores in 1991 and 1994. Both India and China have already introduced bans of plastic bags.

Countries in Africa, Asia, and the rest of Europe have steadily introduced bans (South Africa, Bangladesh and India) or levies (Ireland) on plastic bag consumption.

2. The impact of marine pollution on marine life?

A: Entanglement of species by marine debris can cause starvation, suffocation, laceration, infection, reduced reproductive success and mortality. For example, Antarctic fur seals are commonly entangled in plastic marine debris. Ingestion of plastics by birds and turtles have also been widely reported.

3. why education will likely help to further reduce plastic pollution caused by microbeads and plastic bags at source?

A: Incorporating ocean education, pollution, and waste management in schools could be extremely valuable. For example, a study by found that school children in the UK significantly improved their understanding of the causes and negative impacts of marine litter after education intervention related to plastic marine debris. Education and behavioral change of children is crucial as they represent an important source of social influence among their peers, parents and community.

4. what did governments do to reduce microbeads in cosmetics?

A: For example, 25 UK cosmetics and toiletries companies (e.g., Unilever), have voluntarily phased out microbeads from their products and some supermarket chains (e.g., Waitrose) have already stopped stocking products containing microbeads. In the USA, many cosmetic companies have also been voluntarily phasing out microbeads

3. This article has point out that marine pollution from plastic debris currently become an international problem, which means no one can exclude from this problem. This article is using Canada as example to explore his opinion that microbeads has already becoming a threat in the marine environment, but there remains inadequate or limited policies to address their mitigation.

The 5 Gyres Institute is a 501(c)3 non-profit organization that focuses on reducing plastics pollution [1] by focusing on primary research. Programs concentrate on science, education and adventure (research expeditions for citizen-scientists). Since 2017, 5 Gyres has been in special consultative status with the United Nations Economic and Social Council. The organization's 2015 Expedition was featured in the 2017 documentary "Smog of the Sea," produced by Jack Johnson, who participated in the voyage.
5 Gyres was founded by Anna Cummins and Marcus Eriksen. Eriksen and Cummins have been featured speakers at universities[2] and in news stories.[3][4][5][6] Anna Cummins has also been awarded the Golden Goody Award, during a meeting of the Los Angeles chapter of the USNC for UN WOMEN First Annual Special Assembly.[7] Before founding 5 Gyres, Cummins and Eriksen had worked at the Algalita Marine Research Foundation, with founder Charles J. Moore, who is currently a scientific advisor for 5 Gyres.[8]

What is ghostfishing?
Ghostfishing is a term that describes what happens when derelict fishing gear 'continues to fish'.
Derelict fishing gear, sometimes referred to as "ghost gear," is any discarded, lost, or abandoned, fishing gear in the marine environment. This gear continues to fish and trap animals, entangle and potentially kill marine life, smother habitat, and act as a hazard to navigation. Derelict fishing gear, such as nets or traps and pots, is one of the main types of debris impacting the marine environment today.

Through the Fishing for Energy partnership, NOAA, National Fish and Wildlife Foundation, Covanta Energy Corporation, and Schnitzer Steel Industries, Inc. a cost-free solution is provided to fishermen to dispose of old, derelict or unusable fishing gear and to reduce the amount of derelict fishing gear in and around coastal waterways.

The NOAA Marine Debris Program is working with fishermen to provide a place to dispose of fishing gear free of charge and support new, innovative prevention strategies through technological advancements in fishing gear. These solutions will help prevent derelict fishing gear. The program has collected more than 2.1 million pounds of gear from 41 locations across the United States.

International Convention for the Prevention of Pollution from Ships (MARPOL)
Adoption: 1973 (Convention), 1978 (1978 Protocol), 1997 (Protocol - Annex VI); Entry into force: 2 October 1983 (Annexes I and II).

The International Convention for the Prevention of Pollution from Ships (MARPOL) is the main international convention covering prevention of pollution of the marine environment by ships from operational or accidental causes. The MARPOL Convention was adopted on 2 November 1973 at IMO. The Protocol of 1978 was adopted in response to a spate of tanker accidents in 1976-1977. As the 1973 MARPOL Convention had not yet entered into force, the 1978 MARPOL Protocol absorbed the parent Convention. The combined instrument entered into force on 2 October 1983. In 1997, a Protocol was adopted to amend the Convention and a new Annex VI was added which entered into force on 19 May 2005. MARPOL has been updated by amendments through the years. The Convention includes regulations aimed at preventing and minimizing pollution from ships - both accidental pollution and that from routine operations - and currently includes six technical Annexes. Special Areas with strict controls on operational discharges are included in most Annexes.

Annex I Regulations for the Prevention of Pollution by Oil (entered into force 2 October 1983) Covers prevention of pollution by oil from operational measures as well as from accidental discharges; the 1992 amendments to Annex I made it mandatory for new oil tankers to have double hulls and brought in a phase-in schedule for existing tankers to fit double hulls, which was subsequently revised in 2001 and 2003.
Annex II Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk (entered into force 2 October 1983) Details the discharge criteria and measures for the control of pollution by noxious liquid substances carried in bulk; some 250 substances were evaluated and included in the list appended to the Convention; the discharge of their residues is allowed only to reception facilities until certain concentrations and conditions (which vary with the category of substances) are complied with. In any case, no discharge of residues containing noxious substances is permitted within 12 miles of the nearest land.
Annex III Prevention of Pollution by Harmful Substances Carried by Sea in Packaged Form (entered into force 1 July 1992) Contains general requirements for the issuing of detailed standards on packing, marking, labelling, documentation, stowage, quantity limitations, exceptions and notifications. For the purpose of this Annex, “harmful substances” are those substances which are identified as marine pollutants in the International Maritime Dangerous Goods Code (IMDG Code) or which meet the criteria in the Appendix of Annex III.
Annex IV Prevention of Pollution by Sewage from Ships (entered into force 27 September 2003) Contains requirements to control pollution of the sea by sewage; the discharge of sewage into the sea is prohibited, except when the ship has in operation an approved sewage treatment plant or when the ship is discharging comminuted and disinfected sewage using an approved system at a distance of more than three nautical miles from the nearest land; sewage which is not comminuted or disinfected has to be discharged at a distance of more than 12 nautical miles from the nearest land. Annex V Prevention of Pollution by Garbage from Ships (entered into force 31 December 1988) Deals with different types of garbage and specifies the distances from land and the manner in which they may be disposed of; the most important feature of the Annex is the complete ban imposed on the disposal into the sea of all forms of plastics. Annex VI Prevention of Air Pollution from Ships (entered into force 19 May 2005) Sets limits on sulphur oxide and nitrogen oxide emissions from ship exhausts and prohibits deliberate emissions of ozone depleting substances; designated emission control areas set more stringent standards for SOx, NOx and particulate matter. A chapter adopted in 2011 covers mandatory technical and operational energy efficiency measures aimed at reducing greenhouse gas emissions from ships.

The Honolulu Strategy
In March 2011, NOAA co-hosted the Fifth International Marine Debris Conference (5IMDC) in cooperation with the United Nations Environment Programme and other agencies and organizations. The conference brought the marine debris community together to develop and create a document known as the Honolulu Strategy.
The Honolulu Strategy is a framework for a comprehensive and global effort to reduce the ecological, human health, and economic impacts of marine debris. It is intended for use as a planning tool, common frame of reference for collaboration, and a monitoring tool on multiple levels—global, regional, national, and local—involving the full spectrum of civil society, government and intergovernmental organizations, and the private sector.
Honolulu Strategy Goals
Goal A: Reduced amount and impact of land-based sources of marine debris introduced into the sea
Goal B: Reduced amount and impact of sea-based sources of marine debris, including solid waste; lost cargo; abandoned, lost, or otherwise discarded fishing gear (ALDFG); and abandoned vessels, introduced into the sea
Goal C: Reduced amount and impact of accumulated marine debris on shorelines, in benthic habitats, and in pelagic waters

Recent Government policies and initiatives

Over recent years several UK Government policies have been put forward to address problems with plastic waste. A four point plan to reduce levels of plastic waste was set out in the Government’s January 2018 publication A Green Future: Our 25 Year Plan to Improve the Environment. The UK and devolved Governments have each introduced plastic bag charges to reduce the number of carrier bags in circulation.

Forthcoming initiatives for deposit return schemes for drinks containers, including plastic bottles, have been confirmed by the UK and Scottish Governments, subject to future consultation. The Welsh Government is also reported to be considering such a scheme.

Most recently, at the Commonwealth Heads of Government Summit in April 2018 the Government announced its intention to ban the sale of plastic straws, drink stirrers and plastic-stemmed cotton buds in England. The Welsh Government has indicated that it would be interested in collaborating on the ban. On 27 April 2018 the Scottish Government published a consultation on a proposal to ban the manufacture and sale of plastic-stemmed cotton buds in Scotland.

European Strategy for plastics in a circular economy

As part of its work towards moving towards a circular economy, (where the value of resources are maintained for as long as possible), a European Strategy for Plastics in a Circular Economy was adopted by the European Commission on 16 January 2018. The aim of the strategy is that “all plastic packaging on the EU market will be recyclable by 2030, the consumption of single-use plastics will be reduced and the intentional use of microplastics will be restricted.” The Commission is expected to present a formal proposal on single-use plastics later in 2018. The implications of this for the UK will depend on the speed at which the Circular Economy Package progresses through the European institutions and the outcome of the Brexit negotiations.

UN resolution on marine litter and microplastics

In December 2017 the UK was one of the 193 UN member states to sign a resolution, Marine Litter and Microplastics (UNEP/EA.3/Res.7), at the United Nations Environment Assembly to help reduce the amount of plastic in the world's seas. Under the agreement, an international taskforce will advise how to combat marine litter.
