Earth is the only home we have, and as such, we must treat it with love and respect. If we destroy it, we destroy our own species. We must care for the planet if we care for humankind! Let's be aware of our spending all the resources we have, destroying our trees and with it our clean oxygen, polluting our waters and causing the extinction in huge numbers of flora and fauna. Life always finds a way, and if we ruin Earth as we know it, it might find a way to adapt and form new life, but since this is the only way WE are able to survive, our chances of existing in a non-human hospitable environment don't exist, Save Earth, save yourself.
