It is often reported that we are suffering from more and more natural disasters because of the damaged environment.If we human beings are clever enough, we shouldtake measures to protect the environment right now. If we don't, the earth will perhaps come to an end. We should pass laws to forbid cutting down trees. Those who pollute rivers and seas should be punished. Wild animals should be well protected.
