The earth is about 4,600 million years old. Modern man has lived on the earth for only 35,000 years, but during that time, we have changed our planet(行星) in many ways. Many of the things that we have done are good, but more are not good for the earth.

Water pollution

A lot of people, birds and fish die each day because of water pollution. Factories have polluted the land and the water. As a result, many rivers and lakes are now dead.
