　　Love Makes Beauty

　　With the fantastic spur both in industry and economy，the past 100 years has seen how modernization and civilization has affected mankind. Recently，Copenhagen is being a focus for its Climate Change Conference. A majority of people hold the belief that climate change is the pressing threat for mankind.

　　However，acknowledging the great abundance of harms that the changing climate will bring，I‘d say the most immediate threat is just ourselves. I always imagine a view of life filled with fresh air and various flowers swung in gentle wind. But the reality shows this is a real fantasy. With the fantastically developing industry and the rising number of personal cars，not only the air but also the water is at risk universally. For example，what used to be a pride for Ruianees was Tang River，the clean and clear mother river of Ruian. But with time going by，it was seriously polluted and gradually turned into the biggest block of development. What upsets us most is that such a situation is spreading countryside. It seems that citizens on the earth care little about their land，which directly causes further consequences.

　　How can we deal with environmental problems?There is no doubt that this topic is complicated and unstable as well. But the irreplaceable way，in my thought，is love，love for the earth. It is love that makes beauty，and nothing else will do.

　　Some say love is a river that drowns the tender reed;some say love is a hunger，an endless，aching need. I say love is a flower，and you，are the only seed.

　　Heal the world

　　Nowadays，world leaders are in Copenhagen talking about climate change. Who has such a strong power to gather them from busy work?It‘s our mother——the Earth that has told her kids to start to heal the environment for the pressing threats they are facing now.

　　It‘s commonly thought that lots of countries are blind to the protection of environment while developing the country. And as the quality of life has developed，many families have its own car. As a result，more and more CO2 has caused the earth to be a “Green House”。If no measure is taken，a large number of kids won’t see the lovely and beautiful snow in winter before long.

　　To my delight，some people have been concerned about the environment. The movie <<2012>> is just a good example. It took me 150 minutes to watch the movie. At the same time，I spent a long time considering the meaning which the movie wants to tell people. When the world is at an end，can anyone heal themselves?It‘s obvious that the answer is No. It’s commonly accepted that what the director wants to tell people is that we should take measures to beautify the environment at once or we‘ll die soon.

　　In a word，the environment pollution is a matter of life and death——a matter no country can afford to ignore. People all over the world are supposed to spare no effort to heal the world. Let‘s take action from here and now!

　　Hello, everyone,

　　Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know, food shortages have hit many countries in the world and even caused social unrest in some areas. But who is responsible for the current world food crisis? First, annual world grains output has declined because of climate change. Then lots of farmland has been lost due to the rapid development of industry and urbanization. Besides, faced with the rising energy prices, people have turned to the production of biofuels, which has worsened the severe situation.

　　Then what should we do to deal with the problem? On one hand, we should focus on the environmental protection and improve the ecology. On the other hand, strict measures should be taken to protect farmland. Of course, to build a harmonious world the developed countries should take their responsibilities to help the poor ones experiencing food shortage.

　　As for me, I will call on the people around me to live thriftily. And for the moment, I think, we should study hard to develop science and help solve the food shortage in the future.

　　What Lessons Should Be Learned From the Drought

　　The drought in the south-west China has lasts for several months, which makes people face water and food scarcity. We should learn lessons from it.

　　The drought can be cause by several factors. Firstly, about 63 percent of cities in China are facing water scarcity. The situation is worsened by pollution and industrialization. In addition, too many trees have been cut down, so forest coverage has been decreasing rapidly. What's more, some water conservation projects haven't been functioning properly, thus people there have had to rely more heavily on rainfall for their water supply. Most of China's irrigation systems are very old.

　　In order to prevent this case coming about again, we should improve our awareness of saving water, making proper use of water and recycling water. Meanwhile, we ought to plant more trees and protect environment to prevent loss of water and soil erosion. Of course, the governments should increase investment and repair water conservation projects as timely as possible.
