Do not use a paper cup or paper bags. How to protect the environment has become one of the biggest problems in the world.
We can find that rubbish not only pollutes our environment but also does harms to people’s health. So we should not throw rubbish everywhere. Some factories are pouring waste water into the rivers, the lakes and the fields. It can pollute plants. Sometimes it can kill lots of fish.
We must keep our environment clean and tidy. We have only one earth. We must try our best to protect her, and keep our home more beautiful and greener.A Green SchoolA Green SchoolTake your own bag when shopping and not ask for a plastic bag.
