I think it's our duty to protect our environment. We should save the water and turn off the light when we leave the room. We shouldn't use plastic bags. We'd better ride a bike or walk instead of taking a car. We should pick up the rubbish and throw it into the dustbin. I believe if everyone makes a contribution to the environment, our world will become more and more beautiful.

With an increasing concern over the global warming, we should be more considerate about our environment. The first step in protecting our environment is to recycle everything from news paper to tin cans. The next step is to be more energy conscious. For example, always turn off the light when you leave a room. Finally, to be more environmental friendly, we should start using of the public transportation rather than driving cars.
