In some places we cant see fish 16 in the river or trees on the hills. Some people even have no clean water to drink. Recently, a new life style called low carbon（低碳）life is spreading every corner of our country. The meanings of low carbon are 17 energy and no waste. It is such an important project that I cant wait to express my ideas on how to promote it. First, we should 18 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 19 the no-car day, neither students 20 teachers are allowed to drive to school. Atthe same time, just walk or run. Use ourlegs and enjoy the fun. Second, we had better not use plastic bags 21 . No one can stand the“white pollution”， 22 it is wise to use cloth bags which can be used again and again. 23 ，one thingthat we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 24 the lights the moment we leave, use 25 sides of the paper, and reuse our textbooks and so on. All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these：no-car days, no plastic bags, and no waste. Lets do it now.( )16.

Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet in many ways. Many of the things that we have done are good, but more are not good for the earth.Water Pollution A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.Air Pollution In big cities, factories, as well as cars, trucks and buses are the main causes of air pollution. Many people in cities now have serious health problems. For example, Mexico city used to be a beautiful sunny capital, but today it is always covered by thick brown clouds.Soil Pollution In order to have a good harvest, most of the farmers use chemicals too much in their fields. Thats bad for the soil. But this kind of pollution is difficult to stop.Hope for the Future These problems are very serious for our future, so all of us should do something to improve our environment. If we can stop pollution, our planet will become more and more beautiful and our health will be better. Lets be greener people!
