Originally, we humans are the stewards of the earth. Having the holistic capacity to take care of it, this is not a question at all. But yes - we have become cancer and we are slowly killing the land that gives us life. But I believe we still got TIME...time to revert the earth to its beautiful state. But WE have to do it - not only me, or only them, but US. But if we don't do our part of being stewards of this land, the time left is useless.

Funny thing about us humans, eh? The earth has offered everything we need to live and survive. But now that we have destroyed it, some are exploring if Mars can be a good planet to live. LOL. It doesn't make sense, right?
