Let's Do Something to save Our Environment
We all live on the earth. The earth is our home. We have only one earth. We must take care of it. It gives us the best environment. If we harm it, it will be angry. And then we will have a terrible end. There are three problems in our earth, they are pollution, disaster and illness.
It's our duty to protect our environment. So we must plant more trees, protect the flowers and the trees, save energy, reduce the pollution. We should ask our government to control the pollution from the factories.
Protecting the nature is very important. It's our duty to keep our environment clean and tidy.
If everyone makes a contribution to protecting the environment, the earth will become much more beautiful.
