Dear girls and boys,
　　As we all know, the Earth is in trouble because of the way we are polluting it. Each one of us must do something to help save our planet.
　　Firstly, let’s try not to go to school in our own cars. We should ride our bikes or take a bus instead. Secondly, in order to save trees, why not use used textbooks instead of new ones? Thirdly, we should stop using napkins when we eat in restaurants. Finally, remember to turn off the lights or taps whenever we’re not using them. Of course, that’s not all. We should always do the things we can to help stop polluting the planet.
　　The Earth will be fine again if we all do our best.
