The earth was perfect before the arrival of man. People came and destroyed the beauty of nature, themselves and others. The earth is polluted with landfills, nuclear waste and other debris of our civilization. Therefore, there are global catastrophes. Nature is tired of enduring that it is destroyed and it devours people.
People destroy the earth, but the thing is, destroying the earth, will also destroy them. Not all people are destroying them, but could not take care of it.
