There is only one earth. If it is destroyed, we have nowhere to go. If all kinds of resources on the earth are exhausted. What do these two sentences mean? )

1. There is only one earth. If it is destroyed, we have nowhere to go.

It shows that there is only one planet suitable for human habitation so far. If the earth is destroyed and unfit for human habitation, then human beings have nowhere to go except death.

If all kinds of resources on the earth are exhausted.

Actually, the meaning of this sentence is the same. When all kinds of resources on the earth are used up, there will be no resources available, that is, the earth is destroyed, and people can't survive on it, but wait for death.

Therefore, we should protect the environment and resources of the earth, and we should not patronize the present and ignore future generations.

Protecting the earth is everyone's responsibility!
