Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers. Furthermore, wherever we go today, we can find rubbish carelessly disposed.

There are different kinds of pollutants, each of which comes from different sources. It is necessary to identify the source of pollution, in order to make a policy to eliminate them.

Different products, processes and activities of our industrialized world together form the major source of pollution. The forms of pollution can be mainly divided into three kinds—solid, liquid and gas.

These pollutions have greatly damaged our planet and continue to do so. In fact, pollution is threatening our existence. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even posed a great threat to man’s existence.

We must face the situation that exists and take action to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the public must receive the education about the danger of pollution and so on.

The earth is our home and we have the duty to take care of it for ourselves and our later generation. Fortunately, more and more people have realized these problems. Measures have been taken to deal with these situations by the government. Laws have been passed to stop pollution, I hope the problems will be solved in the near future and our home will become better and better.
