题目内容
12．The environment is everything that surrounds us：plants，animals，buildings，country，air，water---everything that can affect us in any way．The environment of a town，with its buildings and its noise and smells，is a far cry from that of the countryside，with its fields and crops，its wild and domestic animals and its feeling of spaciousness（辽阔）．And the environment differs in different parts of the world．Ecology is the science of how living things exist together and depend on each other and on the local environment．Where an environment is peaceful，the ecology of an area is in balance．
Man is a part of the environment and has done more to upset the ecology than any other living things．He has poisoned the atmosphere and polluted both land and water．He has wasted the earth's natural resources with no thought for the future，and has thought out the cruel ways of killing his fellow men---and every other sort of life at the same time．
Since man has done so much damage，it is up to man to try to put matters right---if it is not already too late．If there is to be any solutions for our ills，that solutions lie in the hands of the young，and the sooner they start doing something about it，the better．
One of the main causes of the earth's troubles is that the world is overpopulated and that this overpopulation is growing at an ever increasing speed．At the same time we are using up our natural resources at an ever increasing speed with no hope for replacing them．
For many years the earth has been unable to provide enough food for these rapidly growing populations and the position is gradually becoming worse since the areas that were once rich have turned into deserts．
Even at this moment many of the earth's natural treasures are being destroyed，many valuable animals and plants are being killed off，and it is becoming increasingly difficult to grow enough food to prevent much of the earth's population from hunger．The situation is getting out of hand．Time is running out．But with your help，we may be able to save ourselves．Who cares？
