We are doing it every day: when we drive our cars, buy that stuff we don't really need, eat too much and then go to gym to keep us fit, wander around the planet to see it with our own eyes. We do it time and again until nothing will be left, or it will be too late to bring it back. Until we will make the Earth so hot, or so cold, or so dry, or so wet, or so acid that we will not be able to live here anymore. Some insects and plants will maybe still be able to live around and maybe it's better this way. We are the people that rule the world and know everything about it, too bad we are that blind.
Or we can try to save it, but that takes a lot of effort, perseverance and relinquishment. Will I do it, will you do it my friend, will all of us do it?
Doesn't this bother you?
