【答案】Our Earth，Our ResponsibilityApril 22nd was named as Earth Day in 1970 and it is celebrated every year.The aim to set up the day is to make all of human beings raise the awareness of protecting the earth，which is the only home for us.As we can see，the earth's ecological environment is becoming worse and worse due to human overuse.As a result，more and more disasters have destroyed our life.So it is high time for us to protect the earth.
Firstly，we'd better not use the plastic bags and it's good for us to use basket or cloth bags.Secondly，we should save water，electricity and energy.For example，we should use both sides of the paper and recycle the bottles.Thirdly，we should plant more trees and flowers.
I think if everyone tries to protect our earth，the earth will become more and more beautiful.
