Answer 1

     We used to have blue sky and white clouds many years ago, but everything has changed now. Air isn't
as fresh as before and water pollution has become a serious problem. Many wild animals are endangered
because people have cut down a large number of trees. We should try our best to protect the environment.
We must make waste water clean again. We mustn't cut down trees or kill wild animals. We must take
action to reduce the pollution and protect our earth.
