I want an essay (more than 400 words) about protecting the environment, and I want to write clearly what I can do for the earth.

The earth is a beautiful and lovely home for human beings. If one day the blue sky is no longer beautiful, the white clouds are no longer kind, the saplings are no longer vital, and there is no singing between people, only mutual isolation and indifference, so that there will never be a pure land in the world. Such a world, are you willing?

No, I don't want to.

I want to be an earth health soldier to save the earth; I want people to know that the result of your violation of nature is that you destroy the beauty of natural landscape, natural dynamics and nature, and at the same time, you are threatened by bad environment.

Nightingale once said: "If you want to live in peace, you must have five essentials.

If I am an earth sanitation warrior, I want to be a diligent helper and clean thousands of households. If I am an earth sanitation soldier, I would also like to be the sun hanging high in the sky, shining every corner of the earth with enough sunshine to make the world more full of vitality. If so ...

Maybe some people are complaining about why heaven is so unfair, but the world has become so desolate in this era. Have you ever thought that if you hadn't violated the ecological laws of nature, you would have today's ending? Don't you know that there is only one earth for human beings? Don't you know that as a resident of the global village, it is extremely shameful to destroy your own village? Haven't you ever thought that you should protect the earth and the environment? Otherwise, where do you want to live? The earth can accommodate you, but you don't understand. Isn't this a sign of your selfishness? Only by understanding it, caring for it and protecting it can we get its sincere return. It's like shouting at the valley, "Hello!" The same friendly answer will come from the valley: "Hello!" This is the harmony between man and nature.

Call for blue sky and clear water, afforestation and elimination of white pollution. We must start with small things. As the saying goes, you can't take Wan Li Road without accumulating steps; If you don't accumulate small streams, you won't be a river.
