We Only Have One World
As is known to all , we have a beautiful world .We can see the sun shining. We can see the moon in a full view. We can see the birds flying in the sky. We can see the horses running on the plain. However, the world is not as beautiul as before, for human beings have brought a disaster to the world.
So it is high time that we should do something to change this situation. As a citizen, we can do much for it. For example, we could use disposable goods less. And we are supposed to save resources such as water, electricity and so on. Also, we ought to plant more trees to reduce the greenhouse effect. In addition, we could try our best to publicize the knowledge of environment protection. Because we only have one world.
