After watching this video, I realise some Pokemon are actually very similar to some real animals. But it is sad that they are endangered because of hunting and habitat loss. The next generation will have no chance to meet them unless we conserve these animals. To save the endangered animals, I think we can start from learning more about the endangered species around Asia and teach our friends and family to protect these animals. Also, people should stop hunting the endangered species for food and fur. 

Will you protect the endangered species? 

In 1944, an American dam expert named J.L. Savage was invited to do field research on possible locations for the project. Two years later, the Republic of China signed a contract with the U.S. Bureau of Reclamation to design the dam. More than 50 Chinese technicians were then sent to the United States to study and participate in the creation process. However, the project was shortly abandoned due to the Chinese civil war that followed World War II.

Talks of the Three Gorges Dam resurfaced in 1953 due to continuous floods that occurred on the Yangtze that year, killing over 30,000 people.

One year later, the planning phase began once more, this time under the collaboration of Soviet experts. After two years of political debates over the size of the dam, the project was finally approved by the Communist Party. Unfortunately, plans for the construction were once again interrupted, this time by the disastrous political campaigns of the “Great Leap Forward” and the “Proletarian Cultural Revolution."

The market reforms introduced by Deng Xiaoping in 1979 emphasized the necessity to produce more electricity for economic growth. With approval from the new leader, the location of the Three Gorges Dam was then officially determined, to be located at Sandouping, a town in the Yiling District of the Yichang prefecture, in the province of Hubei. Finally, on December 14, 1994, 75-years since inception, the construction of the Three Gorges Dam finally began.

The dam was operational by 2009, but continuous adjustments and additional projects are still ongoing.

In such conditions, poor families don't have any money. They can’t afford enough food to keep their children healthy! For the solution to solve this food problem in East Africa, we can use the most direct and immediate solution: provide food aid. This solution can help to save lives. And World Vision can provide treatment of childhood malnutrition, such as Doctor Without Borders. They can help the poor increase incomes, like support for farmers to diversify livelihoods.

The population on the African continent is growing rapidly: For the period from 2000 to 2050 eight of the ten countries

with the highest average annual growth rate in the world are African. Until 2055, 18 out of the 20 countries with the highest total fertility are located in Sub-Saharan Africa. Nigeria as an example is projected to have the third largest population growth in the world from 2000 to 2050. Already now Nigeria is in the top ten of the most populous countries on the planet and expected to climb in the top five in the course of this century. All these are indicators for the enormous ongoing population growth in Africa and they point to the most important fact: The population on the African continent is expected to double from around one billion to almost two billion over the next 40 years (United Nations, 2004).

Larger populations cause higher food demand on the African continent. The nations in Africa will act to ensure that this higher food demand is met by sufficient food supply. But as elaborated subsequently, the big challenge of the 21^st century for the growing number of people in Africa will be to find means to meet their food demand.

Currently Africa ensures food supply by a mix of domestic food production and overseas food imports. West Africa for example depends to 40% on imports in ensuring sufficient rice supply with Thailand as the main rice supplier (FAO, 2010). The total volume of cereal imports in Africa was around 66 million tons in 2010 (FAO, 2013a). This means that for the whole of Africa 30% of all cereals consumed were imported. (Cereals exports are negligible: Even if all exports were instead to be used for domestic consumption, 28% of cereals consumed would still be constituted of imports. (FAO, 2013b)) One of the five largest trade flows of wheat in the world is from the US to Nigeria (FAO, 2013a). Despite domestic production and import efforts there were 239 million undernourished people living on the African continent in 2012, most of them in Sub-Saharan Africa. During the last two decades the number of undernourished people in Africa has increased by more than 35% (FAO, 2012). This shows that food insecurity already now is of increasingly relevant concern. In meeting the rising food demand caused by the growth in population in Africa, there are three options of how this rising demand can theoretically be covered by sufficient food supply: raise overseas food imports, raise domestic food production, or increase both food production and food imports.

Description:
This news is about the food problem in Africa. The first paragraph is mainly talking about the population in Africa.There has 18 out of 20 countries with the highest total population are located in Africa. But, it is still  keep increasing in the future though their total food supply  is not enough.It cases the food shortage and even famine.The growth of population is the main reason of the food shortage.The second paragraph is about the food import in Africa.Amercia is their biggest food import company.Now the Afician depand on food import but it still can't solve the problem and the number of undernourished people in Africa has increased by more than 35%. 

Reflection:
This issue has shown the biggest reason of the food problem is the population growth. But, to solve the problem,the Africa government choose to increasing the overseas imports .I think it is not a good decision.We can't say it is a bad deciosion because it also can help to solve the problem in short time .But ,it is not a long term solving kid. Not only the population growing in Africa, other places will also grow too. If the other contries need food and they can't outport anymore, the Afica will lose the depand and cause more serious food problem . If we want to solve a problem currently and want it to be a long-term action, we must solve from the begining reason . So,we should solve about the rapidly population growth so the demand and supply of food will be equal. First, to educate the people to have an idea to avoid pregment,we must send more information to them and teach them.We can send volunteers to them.Second, they must increaing their own country's food supply. The government and the charity organisation should teach them the farming method that can work in that dry region.They should know about the envirnmental friendly methods so that they can have a long time food supply.Don't be too depend on the overseas import.
Food shortage and famine are very serious problem .Although we are not in Africa, we can still help them like donate some money to let them buy seeds and set up a good farming system.We shoud also cherish to what we have and don't waste food anymore.

charity to them to improve their situation. Therefore, they can buy some clear water and nutrition to address the food problem. Second, we can reduce waste of water and food. For example, we should buy somethings we need and with suitable amount. We also can make a list that we need so that we can avoid to buy some useless things

 

The article is about food shortage in the future. We need to ensure that there are sufficient resources available to feed all seven billion people who live on the earth. But how? Although it seems just a few of people are suffering from hunger, but the United Nations Food and Agriculture Organization (FAO) released figures which show that almost one billion people are chronically undernourished.

Reflection:

After reading this article, I found it unbelievable to believe that in the future, 1/7 of us will suffer from hunger and become malnourished. There is a variety of reasons which lead to this problem. They are inequality in the distribution of food resources, stagnant or declining crop yields, loss of topsoil, the growth in bio fuels, increased demand of meat, and the effects of climate changing. The problem is serious. No one knows whether he will be the one or not. It is related to us, so we need to face the problem directly and positively. What we can do from now on is avoid eating too much meat. Try to use the methods that we learnt from our textbook to protect the environment. For example, to protect the topsoil from loss, we can plant more trees (afforestation) to help avoid soil erosion. Let's try our best to prevent this problem. ^ ^

First is about portage icebergs. Icebergs are very huge. About 90% of an iceberg is under the water. So, it is difficult to portage the icebergs.

Second is about environment. If use icebergs as water resource, people need to portage icebergs, but this will influence the environment. The problem of environment is also serious nowaday. Everyone knows that if the problem of environment more serious, the amount of water will less and less. As a result, portage icebergs cannot help us to have more water. In contrast, it increase the water problem.

Because of these reasons, I think use icebergs as a water resource isn't a good idea, but there are also have other idea to save water problem. For example, people protect the lakes, rivers and seas together and less to pollute the water cooperatively. This can increase the amount of water resources.

I think when people have problems, the most important thing is not to think idea to solve them. In contrast, it is do things cooperatively. Cooperation is a thing that seem simple but difficult to accomplish.

At last, hope people can find more new water resources and don't pollute the water resources again to decrease the water problem.

 the problem of “distribution” of foodstuffs. Currently, the total amount of cereal crops in the world is more than the amount of consumption of 7 billion people. However, there are many people annoying about obese, on the other hand, there are many people dying because of the shortage of foodstuffs. Also, I know the food in the world is not balance. The food in the world is enough to all people.However, the people in rich countries always buy lots of food but they do not need. So the poor can not buy their food easily. Also, people in rich countries always waste their food but they buy a lot. So the food all set in the rich countries and the poor countries just have a few food and the food is expensive to them. The other problem is that the prize of the food is increase. So the poor can not buy food cheap and they also need to face the bad weather. If the weather in the area is bad and hot but a few rainfall, the crops will die easily. People will also no food to eat and the can not sell their crops to earn money. Becauseof these problems, food problem occur.

 

 

With 20 percent of the world’s population,but there are only 7 percent of its available freshwater,China is facing serious water crisis.Since this,economy and urbanization in China is affected.The government is planning massive water projects but its current solutions are far from sufficient. 
  

Reflection: 

We all know how water is important to us.It affects our daily life and also our health.Without water,it’s hard to survive and almost everything become difficult to us.But not just people,animals and plants will also be affected.So we can imagine how would the living things suffer from water shortage.No one wants these things happen,so from now on we must do something to prevent it and we must have the awareness of a crisis. 

The government should set law in enacted to prevent water pollution.Those who found polluting water should pay a fine or face imprisonment.Also,government should encouraged to recycle the rainwater or farmers to adopt farming practice that use less water.They should educated the public on benefits of conserving water.In addition,they should protect forests and improve agricultural practices in targeted areas in China, so that the country can improve water quality. 

On the other hand,we have the responsibility to help for the water scarcity.We can take part in competitions, organizations and societies that aim to preserve and defend natural resources including water.We can also use water wisely like minimize the flushing of toilets and bath times. 

Let us try to alter our habits and lifestyle to save more water than us use. 

From this diagram, we can find that the worldwide grain consumption has been increasing evidently since 1997. It increased from about 1.5 to 2.7 billion tones between 1997 and 2022. It increased 1.2 billion tones in these years. The highest consumption of these three topics is the human consumption which will be about 1538 million tons in 2022. The second one is animal feed which will be about 961 million tons in 2022. 


 

Reflection: 

It is so incredible that it had increased about 1.2 billion in these 25 years. I think the major reasons of the human consumption of grain are the rapid increasing of the population of world and the wasting of people. There are many places like the Sahel are facing food shortage, but we still waste food. In my opinion, we should not waste food by not ordering or cooking too much food if not it is not necessary. 

 

Besides, we can find that the consumption of feeding animals is also awful. I think the cause is people rearing too much livestock for eating. Many people prefer eating meat than eating vegetables. Therefore, it provides the business opportunity for rearing livestock and the demand of grain of animal has increased in recent year. We can eat more vegetables instead of eating meat to reduce the demand of the animals for eating.

Description: 

This article talk about agribusinesses in South Africa. South Africa consider to transform social and economic problem by changing agribusiness. Because agribusinesses use most of the water and it makes the demands for water for urbanisation and associated industrialization didn’t get enough water for work. 

 

Reflection:

After I have read this article, I think South Africa should transform agribusinesses to improve South Africa‘s social and economic problem. First, although agribusinesses is very important of South Africa because the world population will be expected to grow to nine billion people by 2050,it will be a serious problem to South Africa. Second, In South Africa, agriculture uses almost 60% of available water, it cause that another industry cannot work with a enough amount of water. In view of different aspects of this problem, I think that South Africa should do a transformation immediately and absolutely. Even agribusinesses is important to whole country’s people but social and economic problem are also important too. So, if agricultural enterprises have advantages, but others are in a weak position, which may cause serious problems for South Africa. Comprehensive above conditions, I think South Africa should take appropriate measures immediately to improve social and economic problem.

People reclaim lakes for framing ,fresh water fish pond and flatland for urban developement .Because of reclaimation ,the area of Dong ting lake has been reduce a lot . 
Reflection:
I think reclaiming lakes would affect water resources. The Dongting Lake can adjust floods. But Dongting lake become smaller after reclaimation,it greatly reduced the lake's ability to adjust flooding. 
 A large number of reclamation affects the environment a lot. The shrinking of the Dongting Lake has accelerated the flow of fresh water into the sea, the lack of lake water storage capacity, and wasting a lot of fresh water resources.Sand siltation has reduced the Dongting Lake's water storage function too. the sediment deposition in the South Dongting Lake is serious. The sediment deposited in the south of the Dongting Lake reaches three centimeters every year, and the thick place reaches five centimeters.

In this photo we can see that a rich man who has waste a lot of food .But he doesn’t care about that because he has enough money to pay and he doesn’t know about the food problem in the world.Also,we can see that the cook is very thin and I think it show the food problem.

 

Reflection

I know that the waste of food in every year is 1/3 it is a big waste in world but still have a lot of people don’t have three meals in a day.Also when we produce the food we need a lot of time,money and resource such as water and other . It will increase the greenhouse gas.Therefor,I know that if I need to waste less food I should tell my mom and tell she cook less food in every meal then it can waste less also I will tell her that safe the waste every meal.After reading this post and picture,I will try my best to finish all my food in every meal . I will try to safe the waste of the food although I only have a little power but I will try my best.This is the end of my reflection.

The cause of food problems

What are the causes of food problems? 
All of “the factors influence to the system of production, consumption, and divide of foodstuffs” are the cause of food problems.

Increasing world population, the development of the economy in developing countries, and meat-eating dietary habit are also main reasons. 
It’s also one of the reasons that the demand of cereal crops for the builder of Bioethanol and feeding stuff of burn animals. 
Gap between the rich and poor, developed countries and developed countries are also the reason.

There are so many reasons for food problems. 
So, it gets more and more difficult to think where to touch or how to solve. 
And each problems are connecting, so if there is an influence, the influence will affect to all. 
Like if the amount of cereal crops increases, the price of cereal crops gets increasing.

Drought, flood, war, civil war, the appreciation of the price of cereal crops, food shortage, hunger... 
These all are connected. 
Also, there are many problems on back ground of food problems such as population problem, environmental problems, agricultural problems, energy problems, economic problems, the environmental problem of ethnic group of area, income difference, etc. 
It’s hard to make an assertion about what is the origin of food problems any more.

description 

The picture is about what cause the food problem，we can see that the most important is the increase of population. Because of the increase of population, the development of the economy in developing countries, and meat-eating dietary habit are also main reasons. Also,it talk about the other reason that cause food problem.

reflection 

I agree with the article. I think that the most important reason of causing the food problem is human and the increasing of population. I think the increase of population affect the food demand.Actually, I think the food in the whole world can solve this problem. However, the economy in different countries is very different. The distribution in the world is uneven.Like the article say,“Gap between the rich and poor, developed countries and undeveloped countries are also the reason.”I am very agree of this sentences. So,the food problem increase.I am very sad with this problem, I think that the developed countries should do something to help the undeveloped countries like Sahel and Brazil. They can help them to develop the technology, give them some money or teach them how to develop the farming.For the other problem that cause the food problem, I think that we can not stop the physical problem like the drought and flood but we can reduce the rubbish to reduce the physical problem.

 

 
 

Description: Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. 97% of the water on the Earth is salt water and only 3% is fresh water. So the edible water is very precious.

Because of the lack of water resources, many questions have been raised. First, Inadequate access to safe drinking water by over 1.1 billion people. Second, Groundwater overdrafting leading to diminished agricultural yields.Third, Overuse and pollution of water resources harming biodiversity. Fourth, Regional conflicts over scarce water resources sometimes resulting in warfare.

For such a situation, some countries propose that desalinated seawater can be used as a freshwater supply. Desalination of sea water can be done either via distillation or membrane process. However, both process requires large amount of energy and thus costly, which means desalination remains an expensive option for providing reliable fresh water supply, restricted to only economically well-off countries.

However, I think that the best solution to the problem of insufficient water resources is to cherish water.

Finally, on December 14, 1994, 75-years since inception, the construction of the Three Gorges Dam finally began.

The dam was operational by 2009, but continuous adjustments and additional projects are still ongoing.

Reflection:
Building the three gorges dam had used up a lot of money. Of course, you can say that it is very useful to control flooding. But what problems would happened then?

When the construction is  working, people have to move. So, it will use up more and more money for people to live in a new place. We always say that we have to protect the environment and animals as they are very important to our world. Without them, our ecosystem will be affected. Then, our world would be more and more worse. It will strongly affect our earth. If some of the animals die, the food chain will also be affected. If the food chain is not good enough, it will completely affect human. even though human is the top of the food chain, we can eat all the living things. We are not required just eat one thing, but different people need different food. Therefore, building the three gorges dam is a wrong decision.

besides, the government always say that they need to give out more money to improve our environment. Yes, It seems that it is very good. But why do they still built the dam to destroy our environment. Don't you think it is very contradiction? Why don't they protect the environment in Chang Jiang first? It is a very big problem now! Just because of this thin, I think that the Chinese government is very hypocritical, I think they just want to let the people to trust them that they are response to the Chinese people. It is very treacherous!

In addition, the government is very stupid because i think that when they are building the dam, people have to move to a new home. It cause more expensive and if the dam collapses, it will hurt more and more people. Flooding killed a lot of people, after building the dam, people may not be flooded and killed, it seems that building the dam had protect more people, but I don't think so. If the dam is damaged and collapses, it may hurt more people, more and more people may die. Also, the dam let the land in downstream become unfertile, without farmland, food production decrease, not enough food, people may become hunger and finally they will die. There is the same result, so why do the government still built the dam, it had already killed about 30,000 people when building it.Also, it may let people die, and it needs to use a lot of money at the same time. Is it good? No, I don't think so. It is a stupid decision. In addition, why do Chinese people had to listen to an American person's idea? Are they a pig? It must not the best choices to build the dam. Of course, there is a lot of bad causes from building the three gorges dam, but I think that it's enough to prove that building the dam is not good.

Totally, I think that build the Three Gorges Dam is a worse decision.

The photo below shows the water problem in hk in 1960s.The people were facing drought.

Why ?Because the population increased fast，so the demand of water increased. However,the water supply wasn’t enough.So there were only four hours of water supply per

four days because there was not enough water.

 

Reflection:

After so many years,I can still imagine how serious the problem was in a big city like Hong Kong.Lives are affected because of the drought.People cannot live normally.They need to use water frugally.They cannot take showers.They cannot completely wash the rice.So people would easily get sick.The government try to buy DongJiang water from China to solve

The drought.And the government built Plover Cove Reservoir.The problem was finally solved.I think we should be Thanksgiving about why we don’t need to face the problem nowadays.And I suggest the hk government should educate hong kong people not to waste water.Because global warming would affect the weather in hk.HK Observatory found out that there will have a dought in this century.Therefore people cannot waste water.
