Landfill Waste(Mammoli):

1) Definition- Landfill waste includes materials such as plastic, paper, metals, and organic waste, disposed of in landfills without advanced recycling or reuse treatments.

2) Positive Aspect- The methane produced from decomposition can be recovered and used to generate energy. If well managed, landfills can reduce air pollution and allow the recovery of some materials.

3) Negative Aspect- Soil and water pollution, methane emissions harmful to the climate, large space occupation, bad odors, and the proliferation of insects and rodents.

4) Example- An example of a harmful landfill: The Malagrotta Landfill, near Rome, caused pollution and greenhouse gas emissions. Closed in 2013, it is now undergoing remediation and biogas recovery for energy

5) Your Point of View- In my opinion, these problems origine from inadequate waste management and the lack of more sustainable solutions.

# data[].attributes.body
1. Definition:

Public transport means buses, trains, trams, or the metro that many people uses to move around.

2. Positive effect:

• Fewer cars on the road

• Less pollution and cleaner air

• Saves energy and helps the planet

• Less traffic in the city

3. Negative effect:

• Old buses and trains can pollute

• Sometimes they are crowded or not on time

• Public transport doesn’t arrive everywhere

4. Example:

In my city, people take the bus to go to school or work, It’s better than 30 cars on the road, there is less traffic, less pollution and help people travel between cities.

5. My opinion:

I think public transport is a good thing. It helps the planet and also people who don’t have a car.

Fossil Fuels

1. Definition:

Fossil fuels are things like coal, oil, and gas that come from plants and animals. People burn them to make energy for cars, homes, and factories.

2. Positive effect:

Fossil fuels give us a lot of energy to power things we use every day, like light bulbs, cars, and machines. They help people travel, cook food, and stay warm in winter.

3. Negative effect:

When we burn fossil fuels, they make dirty air and add gases to the sky that make the Earth hotter. This can change the weather and hurt animals, plants, and even people. It also takes millions of years to make fossil fuels, so one day they might run out.

4. Example:

Cars use gasoline, which comes from oil (a fossil fuel). When we drive, the car burns the gas and makes smoke that goes into the air.

5. My opinion

Fossil fuels are useful, but they can be very bad for the planet. I think we should use other kinds of energy, like wind and sunlight, so we don’t hurt the Earth as much and we can be more sustainable.

DO:

Turn off the lights when you leave a room: even if you think you'll be right back, turn off the lights make the difference.

Unplug devices: it is important to unplug devices when they're not in use.

Install a solar panel: even a small space on the balcony is enough to install a self-generating solar energy.

Choosing and using household appliances well to save energy: always opt for a high- rating and low-consume appliances, from A and up (the most efficient).

DON'T:

Don't leave the fridge door open for too long: every time you open the fridge, cold air escapes and energy consume increases.

Don't leave electronic devices on standby: completely turn off electronics when they're not in use to avoid the waste of energy.

Don't waste hot water: hot water takes a lot of energy to heat, so use it with attention.

Don't open the oven often during the cooking: each time you open it, you will lose heat and the oven has to work harder to get that back

1) definition : Endangered animals are species of animals that are at risk of disappearing forever due to factors such as: destruction of habitats, illegal hunting, pollution or climate change.

2)positive effects : some contributions we can make to avoid the extinction of some species are: maintaining the balance of ecosystems, increasing the level of security to avoid illegal hunting and not destroying their habitats. since each animal has a specific role in the food chain and in biodiversity

3) negative effects : some negative effects are: at an economic level because to protect some species of animals a lot of money is needed and sometimes they can't even be saved and therefore the species becomes extinct and also because with the extinction of a species there is the risk that the whole food chain is destabilized

4)example: an example is the giant panda in china which for many years was considered an endangered species, but thanks to conservation programs, nature reserves and the fight against illegal hunting, the giant panda has gone from endangered to vulnerable species on the iunc (international union for conservation of nature) list

5) opinion In my opinion it is important to protect animals in danger of extinction because each animal is fundamental to the food chain and also because each species has a unique value for the ecosystem, even if it is expensive and demanding to protect these species it must be done to guarantee the balance of nature also because our survival depends on a healthy environment

What is noise pollution?

It is an annoying sound that disturbs and can harm the health of people, animals and the environment. It can also create problems in doing daily or work activities.

Negative effects of sound pollution

One negative effect of noise pollution is that it can cause stress and difficulty sleeping. When there is too much noise, the brain cannot relax well, which can make us feel tired, nervous, or even sick over time.

Example of sound pollution

A simple example of noise pollution is when you live near an airport and hear the loud noise of planes taking off and landing all day. This noise can be annoying, make it difficult to sleep, give headaches and stress people. Even animals nearby can be disturbed. It is a problem because the noise is too loud and continuous.

Point of view

Noise pollution is a problem because too much noise can ruin your quality of life. Think about it: when there is always noise, such as traffic, sirens or factories, it becomes difficult to relax, concentrate or even sleep well. This is not only bad for people, but also for animals, who can become scared or have difficulty living in their natural environments. Reducing unnecessary noise means creating a quieter world, where everyone can live better.

Definition:

Recycling is a process of collecting materials that would be thrown away as waste and reuse them.

Common recyclable materials are: paper, plastic, glass and some more.

Positive effect:

Recycling helps to reduce pollution and decrease the amount of waste in landfills, it's a perfect way to create a sustainable environment.

Negative effect:

Recycling has many positive effects but also negative ones.

First of all, the process requires high costs for collecting, transporting... and it also produce greenhouse gas emissions.

And last but not least, if not separated properly, recycling can be harmful, requiring landfill.

Basically everyday we need to throw something in the trash bins, but we can't throw it anywhere we want.

It depends from the material of the object.

In fact based on the materials you need to throw the trash in his specific rubbish bin and try to do it carefully without making mistakes.

We can also reuse things instead of throwing them away, like plastic bottles after we finish them.

To be honest I don't care a lot to do the recycling, so sometimes I just throw the rubbish away anywhere I want, I know it's bad but I still don't sort the recycling, but I admire everyone who care about it.

Definition:

Conservation is the protection, preservation, management, or restoration of natural environments and the ecological communities that inhabit them.

Conservation should to Avoid Exploitation of Natural Resources to Keep  balance in our ecosystem, to prevent Human-caused natural disasters and finally should help to reduce the impact of global warming.

Positive effects of conservation:

Conservation helps to ensure we not only save species from destruction. but help preserve the environment we ourselves live in.

A good global conservation programme should prevent habitat destruction, safeguard endangered species, and maintain the delicate balance of ecosystems.

Negative effects of conservation:

Most nations and conservation agencies have limited financial resources.

Also it can be hard to choose where to focus our efforts.

The implementation of effective conservation measures can be complex, requiring  strong political will, scientific expertise and community participation.

It can face opposition from landowners, industries and governments.

Practical example of conservation:

The most important example of conservation are:

Protecting biodiversity.

stopping the use of fossil fuels(oil and coal)

Using alternative energy resources such as solar, wind or water energy.

Planting trees.15 billion trees are cut down each year.

Establishing protected areas.

Hunting restrictions

My opinion about conservation:

In my opinion it will be essential to implement conservation policies globally very soon if we want our fragile planet to survive.

Only by doing so can we guarantee climate stability, biodiversity, clean air and water, and  a decent quality of life for the generations to come.

1. Definition:

Water pollution is the contamination of rivers, lakes, seas, and groundwater due to harmful substances like waste, chemicals, and bacteria. This makes the water dangerous for humans, animals, and the environment.

2. Positive Effects (if any):

In rare cases, some pollutants, like agricultural fertilizers, can help aquatic plants grow, providing food for some animals. However, this is only temporary and often leads to bigger problems, such as excessive algae growth that harms other aquatic life.

3. Negative Effects:

Water pollution has many negative consequences:

• For health: Contaminated water can spread diseases like cholera and hepatitis.

• For animals: Many fish and other aquatic creatures die due to toxic substances.

• For the environment: Too many chemicals in the water can reduce oxygen levels, suffocating marine life.

• For the economy: Pollution damages industries like fishing and tourism, causing financial losses.

4. Practical Example:

A famous case is the Flint water crisis in the United States. In 2014, the city’s drinking water was contaminated with lead, causing serious health problems for residents, especially children.

5. Personal Opinion:

Water pollution is a serious problem that affects everyone. Even though it may have small positive effects in rare cases, the damage it causes is much greater. Governments, businesses, and individuals must do more to protect water, as it is an essential resource for life.

Greenhouse gases

Definition: Greenhouse gases (GHG) are gases such as carbon dioxide (CO₂) and methane (CH₄) in the atmosphere that trap heat, keeping the Earth warm enough for life.

Positive effect: Naturally, GHGs maintain the Earth's temperature, allowing life by keeping the planet warm (about 59 °F/15 °C) enough for plants, animals and humans to survive.

Negative effect: Human activities (such as burning fossil fuels) increase GHG, leading to global warming. This causes climate change, rising sea levels, adverse weather conditions and loss of ecosystems.

Practical example: Deforestation releases stored CO₂, increasing GHG and worsening global warming. It also reduces the ability of trees to absorb CO₂.

Personal opinion: While GHGs are essential in moderation, excessive human emissions are damaging the planet. We must adopt sustainable practices to reduce their impact and protect the Earth's future.

Donating to charity means giving money, things, or time to help people or organizations in need. It can be done through money donations, volunteering or other example.

2. How It Helps the Environment

Charity donations can help the environment in many ways:

Giving money to organizations that plant trees helps reduce CO₂.

Donating to recycling charities helps reduce waste.

3. Negative Effects (If Any)

Even though donating is good, there can be some problems:

Lack of transparency: Some charities do not use the money correctly.

Unwanted waste: Donating things that are not useful can create more trash.

4. Practical Example

A real example is donating to WWF to help save endangered animals. The money helps protect forests and supports projects to keep animals safe.

5. Personal Opinion

I think donating to charity is a very good thing. But it is important to check if the organization is honest and really helps. Also, giving time and effort (like volunteering) is just as important as giving money.

1 Definition: Air pollution refers to the contamination of the air with harmful substances that can negatively impact human health, the environment, and climate. These substances can include gases, particulate matter, and other chemicals released into the atmosphere from various sources.

2 Positive Contributions: There are no positive contributions of air pollution

3 Negative Effects: Air pollution has a wide range of harmfull effects on both human health and the environment.

- Human Health: It can cause respiratory problems, cardiovascular disease, and even cancer. Children, old people, and people with pre-existing health conditions are particularly vulnerable.

- Environment: Air pollution can damage ecosystems, acidify lakes and rivers, and contribute to climate change. It can also harm crops and livestock, leading to food insecurity.

4 Practical Example: A common example of air pollution is the smog that often forms over cities. This smog is a mixture of gasses from vehicle exhaust, industrial emissions, and other sources. It can reduce visibility, irritate the eyes, and make it difficult to breathe.

5 My Point of View: Air pollution is a serious problem that requires attention. We need to implement technologies to reduce emissions and protect our air quality, and we all have a responsibility to contribute to its preservation.

1.DEFINITION

A petition is composed of the signatures of several people and serves to report a problem or support an environmental cause.

2.POSITIVE EFFECT

Petitions are useful for making people aware of environmental problems and can push institutions or governments to act for the environment nd adopt more sustainable measures.

3.NEGATIVE EFFECT

petitions may not attract enough interest to be accepted, or they may be ineffective if they do not have a sufficient number of signatures, tuttative anceh if a petition obtains many signatures it may happen that several of the people who have signed do not really commit themselves to the cause.

4.EXAMPLE

a famous example of an environmental petition is the one launched against deforestation of the Amazon forest in Brazil to stop illegal logging and safeguard indigenous peoples.

5.MY OPINION

petitions can help to make people understand the importance of many issues such as the environment, also it is important to give your own contribution sell argument if you sign for a possible cause.

1) Definition of climate change:

Climate change is the long-term change in temperature, it is mainly caused by fossil fuel combustion and intensive farming.

2)How it contributes positively to the environment:

Climate change is not positive, but it has made people more aware of taking precautions to safeguard the environment ES (Use of renewable energy)

3)Negative effects of climate change:

The negative effects are significant. For example, the rise in sea level, which leads to flooding in coastal cities. Another phenomenon that is occurring often in these years are the most extreme weather events (hurricanes, droughts, floods)

4)Practical example:

An example of climate change is the melting of ice in the polar regions. With increasing temperatures, the ice melts faster, causing the sea level to rise, which can flood cities.

5) My point of view:

I think that climate change is a very important problem but it can be solved with the commitment of all people.

DEFINITION: Is the variation of climate situation at global and temporal levels: is an increase of average global temperatures with weathers conditions associated . It have been developing since XIX century. The principal causes are: increase in the concentration of greenhouse gases in the atmosphere (CO2 and others); changes on the earth's surface as deforestation; increase in aerosols; intensive farming.

POSITIVE AND NEGATIVE EFFECTS: There aren't real positive effects for the environment but many people supported the idea that global warming will might benefit agriculture, reduce heating costs and may even boost tourism but is more probably that this effects will be in negative in facts there are multiples evidents effects how: melt of glaciers and increase of water in oceans; decrease of precipitation with drought and desertification in some area of the world and in other increase of alluvions with floods and ruin of cities; frequents weathers swings; loss of biodiversity.

PRACTICAL EXAMPLE: there is a reduction of water availability; increase of request of energy; bioclimatic discomfort; bad quality of air; hotter summers.

MY OPINION: Global warming is a natural process of evolution of earth but we have sped up of double this process with the industries, tecnological advancement, exploitation of naturals resources.... The problem can't be eliminated but only attenuated, anyway is difficult do this for the actual situation and little is being done, if the things will not change, in the nexts centuries the negative effects could tripled or more.
