But our environment is becoming worse and worse. It s very bad for our life. Now many people have air-conditioners and cars, they produce (give off ) waste gas. More and more trees are being cut down. There are so much sand on the earth (leaving only sand ) . We often see factories pour waste into rivers or lakes. Water in the river is quite dirty. We haven t enough clean water to drink in cities. Now we are in danger. It s very necessary and important to protect the environment well.
I think if everyone tries his best to protect the environment, the world will become much more beautiful , and our life will be better and better .
