nowadays,population as well as environment has become a very important problem.

　　with the development of china ,the population is growing faster and faster,though,chinese government has put forward strageties, such as ,one child policy.but at the same time ,the increase has slown down,which is to our relief.

　　as for the environment,the biggest problem is that people do damage to it and seldome do they protect.so,we would like to say,if they still don·t stop those silly mistakes made to destroy the environment,one day ,human beings will be the last creature in the world. protect the environment!our earth is our mother for all of us.
