In
the past, man didn’t have to think about the protection of his environment.
There were few people on the earth, and natural resources seemed to be 36.
Today
things are 37 , and the world has become too 38 . We’re using up our natural
resources too quickly, and at the same time we are 39 our environment with dangerous
chemicals. If we continue to do this, human life on the earth will not survive.

and more trees.

this.

present rate, in a few years there will not be enough food . What can we do to solve these
problems?

recycle them.

world population will not rise so quickly if people use modern methods of birth
control .
Finally,
if we educate people to think about the problems, we shall have a better and
cleaner 47 in the future.
