大气污染英语作文六：Air pollution

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.


大气污染英语作文七：Air pollution

The cartoon presents the Earth with a personified human face that seems quite unhappy. A examination of the picture immediately reveals that the source of its mood is the air pollution resulting from a huge number of automobiles spread around its surface.

The cartoon, no doubt, aims at alarming humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, the majority of people merely indulge in the celebration of the convenience brought by cars, while forgetting or simply neglecting their harmful impact on the atmosphere. Admittedly, there are various factors contributing to the current worldwide air pollution, but it is undeniable that the exhaust from automobiles is categorized as one of the major elements.

I would like to make the following proposals to solve this problem: firstly, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. It should also be guaranteed that the clean energy be inexpensive so that it can be widely accepted. Besides, there should be attempts to develop possible transportation means, so that citizens can be diverted from dependence on cars. In short, it is humans' responsibility to resume clean air for Earth.


大气污染英语作文八：Air pollution

Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage.

They can travel hundreds of miles in the wind before falling to the ground in the rain. But this "chemical rain" gradually destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country＇s trees had been damaged by the year 1986.    

Time and time again there are serious accidents that pollute the air.  

In 1986 there was a bad accident at a nuclear power station in Russia.  

A cloud of radiation crossed the whole of Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by this accident.In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured.  Many of the injured lost their sight.
