The earth is our home.We must take good care of our home!We must keep the land,the water and the air clean.
Now there is a lot of pollution in our home.
Long long ago,the river and the sea were very clear.But we can't see the clear water now.Why?Because of the pollution.People often wash the clothes in the river and they often swim in the river in summer.It's nothing serious at first.But the longer the worse.Recently,there are many factories in the city.They pour waste water into the river near them.The rivers become vere dirty soon.Lots of fish are dead.How terrible!
At the same time,there is much waste air from the factories,cars,buses and so on.We can also hear a great deal of noise.
Many people throw waste on the ground.Sometimes,some people spit in a public place.Oh,my God!How dirty!
There were many trees long ago.But now people cut down many of them.The wood is used to make the desks and chairs.So many lovely animals have no home.They have to stay in the zoo.
Please stop doing such things!Taking care of the environment is very important.Pollution is bad for our health.If we want to live longer,we must make a contribution to protecting the environment.If everyone does as I said,the earth will become much more beautiful.
