Protect Our Earth
Our earth is not what it was before.In the past,it was very beautiful covered with trees and grass and surrounded by fresh air.We live a healthy and happy life on it,without pullution.
But with the development of economy,many facotries have been seen set up,pouring poisonous gases and water into the rivers and lakes every day.The air isn't clean and neither is water.Meanwhile,thanks to too much carbon dioxide let out by thousands of cars,the earth is getting warmer and warmer,causing the climate change and rising of the sea leval.It is believed that the area of land is getting smaller and smaller while the area of sea is greater and greater.
For these reasons,we should do something to protect our earth.As a students,we should not use plastic bags when shopping.We should litter everywhere.We should save water and use two sides of paper.
