Pollution around us
In recent years our life isbecoming better and better.But our environment is becoming worse and worse.It’svery bad for our life.Now many people have air-conditioners and cars,theyproduce (give off ) waste gas.More and more trees are being cut down.Thereare so much sand on the earth (leaving only sand ) .We often see factoriespour waste into rivers or lakes.Water in the river is quite dirty.We haven’tenough clean water to drink in cities.Now we are in danger.It’s verynecessary and important to protect the environment well.I think if everyonetries his best to protect the environment,the world will become much morebeautiful ,and our life will be better and better .
