There are many ways to save the environment. In this passage, you can learn some ways.

    Plant more trees.

    (挑选) a right ground near your house or workplace. Unless there's any rule(阻止) you from growing trees in that area, go ahead and grow trees. Plant a tree every month and(鼓励) your friends to join you. Have more and more trees planted and there will come a day when you have green(陆地).

    Walk more and drive less.

    Choose to walk rather than to(驾驶) your car. Walk or ride a bicycle to work if it's not very far. Not only cycling but also walking is good exercise, And each time you avoid using your car, you're doing something(有帮助的) to cut down on air pollution. You are saving fuel, saving money and keeping fit as well.

    Save water.

    Water is very(重要的) to living things. We use and pollute it. The simplest way to save water is turning off water taps(在...之后) using water. When you visit a beach, make sure that you don't throw waste around. Don't pollute rivers by dropping(垃圾) or other waste. Water is so precious, so we (一定不要) waste or pollute it.
