Saving the Earth
How to protect the environment has become one of the biggest problems in the world. There are many kinds
of pollutions around us, such as air pollution, noise pollution, water pollution and light pollution. We can find that
rubbish not only pollutes our environment but also harms people's health. So we should not throw rubbish
everywhere. Some factories pour waste water into the rivers and the lakes. The behavior of these factories will
pollute the water, and sometimes it can kill the fish living in them.
We have only one earth. We must keep our environment clean and tidy. We must try our best to protect her,
and make our home more beautiful.
