Saving the Earth
How to protect the environment has become one of the most serious problems in the world.Rubbish can pollute the envionment and it is harmful to our health.So we should not throw rubbish away.Worse still,some factories put the dirty water into the rivers,lakes and the field,it kills many fish and it does great harm to the grops.
I think we should remember that we have only one Earth,we should try our best to protect the environment to make our world more beautiful.
