We Must Protect Our Ecological System

With the development of human civilization, man has created countless wonders, but at what a price! Our ecological sys-tem, on which all animals' existence depends, has been seriously damaged and is still being threatened. The earth's temperature is getting higher, more and more forests are being felled, large numbers of animals are facing extinction, and deserts are expanding at an incredible rate.

The causes for the worsening ecological system are manifold. Perhaps two of the major problems lie in people's pursuit of short-term interests with little attention to long-term interest sand their pursuit of individual interests rather than collective interests. In the first case, many lakes are filled to grow crops or even build houses; trees are cut down, only bare mountains stand cold in the wind and are capable of holding no water when it rains. In the second case, scenic spots become dirty and deserted because of newly established nearby factories producing waste water and air; industrial countries invest heavily in chemical factories in the Third World nations, keeping their own land relatively clean.

To solve the problems mentioned above, we should try our best to balance short-term interests with long-term ones by making long-term plans and taking as many things as possible into consideration. We're living today and are still to live tomorrow we and our posterity both have to live on the earth. Besides, Global action should be taken to protect our ecological system. People, eastern or western, rich or poor, should join their hands to prevent our ecological system from being further damaged. We have only one earth and we have to make it a better world.
