Heh, no I don't worry about the planet. The planet has gone through so much (e.g. earthquakes, ice ages, tectonic shifts, magnetic polar reverses, meteors) it has been here before us, and probably will be here long after we're gone.
My point of all that post was to humble our
superiority complex that we are somehow responsible for all the good things in this planet, when clearly, it has been an organic process. All species have gone through the evolutionary ladder, but we(homo sapiens) are in this game for so long before we are recycled and replaced by other species. (and who knows, it could be these ants who will replace us some day lol)
