as we all know，the environmemt around us is getting worse and worse .in some places，we can't see fish swimming in the river or trees on the hills. some people even have no clean water to drink. so i think we must do something to protect the environment. but what can we do?how to protect our environmemt ?for example，we can go to school on foot or by bike . we can use shopping baskets not plastic bags when we go shopping，and we can use both sides of the paper when we write .in a word，if everyone pays more attention to our environment ，there will be less pollution and our life will be better。“there is only one earth”，i hope everyone will protect our environment well。
