The earth is our home, but it's getting dirtier and dirtier. Eve- rybody should do something to protect
the earth. As students, we need to do some little things. For instance, we should turn off thelights before
we leave the classrooms, try to ride our bikes to school instead of going by bus or by car, try not to throw
garbage everywhere, recycle waste paper and bottles or use them again for something else, bring a
shopping basket instead of plastic bags, try to save water and electricity, and call on young people to plant
more trees in our neighborhoods so that the environment can become bet- ter than before. If everyone
gives a hand to save our environment, our world will become better and cleaner.
