关于空气污染的英语作文，急！

In the past few decades, our Earth has changed a lot, but to the bad direction. Among these changes, the air pollutions resulting from a huge number of automobiles and coal-burning is almost the severest. The severe air pollution alarms humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, with the deepening of urbanization, more cars are needed, which will make the air pollution worse. Therefore, the following actions should be taken. First, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. Second, try hard to develop possible transportation means, which are enviromental friendly. So that the citizens can reduce the dependence on cars. In short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem.
在过去的几十年中，我们的地球发生了很大变化，但是是往坏的方向。在这些变化中，大量汽车和煤燃烧产生的空气污染是最为严重的。严重的空气污染警告人类，我们无休止的的生产和使用汽车给我们的地球带来了沉重的负荷。然而，随着城市化的加深，汽车的需求量也越大，这会导致空气污染更严重。因此，我们应该采取以下行动。首先，我们应该运用最尖端的技术，以新型能源作为化石燃料的替代品。其次，努力寻找可能的环境友好型交通方式。这样城市居民就可以减少对汽车的依赖。简而言之，人类应该承担空气污染的责任，寻找解决这一问题的方法。

篇二：
Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.
　　Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.
　　We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are　still put into rivers.
　　We know that if the population continues to rise at the present rate, in a few years, there won't be enough food.What can we do to solve these problems?
　　If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.
　　Our natural resources will last longer if we learn to recycie them.
　　The world population will not rise so quickly if people use modern methods of birth control.
　　Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment.
However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
