In recent years our life isbecoming better and better.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 seefactories 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’svery necessary and important to protect the environment well.I think ifeveryone tries his best to protect the environment,the world will become muchmore beautiful ,and our life will be better and better .
