ããThe area of desert in the world is growing every year. Many parts of the world which once had large populations and produced plenty of crops, have become deserts. Dunhuang in China, deep in the heart of the Gebi Desert, was once a great city.
ããCattle are one cause of the problem. In good years, famers increase the numbers of their
cattle. Then one year, the rains fail to come. The farmers do not want to kill any of their cattle, so the cattle eat ail the grass and anything that grows on poorer land. If this continues for several years, the grass never grows again and the land becomes a desert. One suggested answer is for farmers to limit the numbers of their cattle.
ããAnother problem is that good soil is gradually lost. When trees are cut down, there is nothing to hold the soil in place on the hillside. So when if rains, the soil is washed down the hills and into the rivers. Strong winds can also blow away the valuable soil that lies on the top of the fields.

ããPresently, a new lifestyle called low carbon life is spreading every corner of our country. The concepts of low carbon are low energy and no waste. It is such a significant project that I canât wait to present my ideas on how to promote it.
ããOn the first place, a no-car day is supposed to set up every week in our school. Becau
se cars not only cause serious air pollution but also waste energy. On no-car day, neither students nor teachers are allowed to drive to school. Meanwhile, just walk, jump, cycle or run. Use our legs and enjoy the fun.
ããOn the second place, we had best not use plastic bags any more. No one can stand the âwhite pollution2020各省高考时间â. So, it is wise to use bags which can be reused again and again.
ããFinally, one thing that we should keep in mind: every big thing comes from the subtle. Therefore, as students, we ought to turn out the lights the moment we leave, turn off the tap in time, and reuse our textbook and so on.
ããAll 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 day, no plastic bags, and no waste. Letâ一平方千米等于多少公顷s do it now.
ããToday's society is a highly developed technological society. However, the shortcomings in the development process are obvious, such as: carbon dioxide, and environmental pollution. But the most serious should be the carbon dioxide problem.

ããNow the problem of global warming because of excess emissions of greenhouse gases. Excessive amount of carbon dioxide emissions, creating a diversified economy and La Nina phenomena lag disorder. Two levels of glaciers melting, polar animals lose their chance of survival at the same time, will lead to rising sea levels, many coastal cities into the water did not result in a few years later. Therefore, we must take the necessary measures to reduce the environmental impact of carbon dioxide. From For example: tree-planting activities, reduce fossil fuel use, we can from our own, to promote low-carbon living.
ããCurrently,my school is launching an activity whose theme is that actions change the world to advocate the low carbon living.
ããIn the activity,we are required to go to school or some other place by bike or by foot as much as possible instead of by bus.And when the Christmas comes,sending e-greeting cards instead of tridional cards of which are made of wood as we know.Besides,we should use both sides of every piece of paper and we should save water as well as electricity.
ããI believe that only we do thus can we have a better living environment.

ããThere are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to peopleâs health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
