题目内容：

Our environment isn’t as green and beautiful as it should be. There are steel(钢铁) monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the earth.

You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.

At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps（水龙头）are not leaky（漏的），which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It is not only energy-saving, but also cuts down electricity costs.

Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.

Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.

With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.
