How to maintain the ecological balance under the climate change
Once human beings 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, but the world has become too crowed now.
We can see that air has become more and higher in everyday. In summer, we feel hotter than unusual.
Also, we are using up our natural resources, polluting our environment and so on. In a word, we have explored too much and demanded too much from the mother nature.
If we continue to do this, human life will not survive on earth. We realize that if too many fish are taken from the sea true will soon be none left. We know that if too many trees that are cut down, forests will disappear. And if the deforestation has achieved a certain degree, the whole ecological system may be destroyed.
What can we do to solve these problems? If we plant more trees, the air will become pure and fresh. If we eat more vegetables and less meat, there will be more food available. Our natural resources will last longer if we learn to recycle them. Finally, if we educate people to think about the problems, we shall have a better and clearer planet in the future.
