The earth is doomed. Not a question of if, but when. It's the only reasonable way to look at this situation. I won't go as far as to call humans a disgrace (or a plague for that matter), but the way we live is stupid and it is only a matter of time before quality of life is garbage across the board. Good riddance, because the better things are, the more likely we are to want to stay living here. I'll try not to let the atmosphere hit me in the ass on the way out.
Through many of samsara’s births I hasten seeking, finding not the builder of this house - pain is birth again, again. O builder of this house you’re seen, you shall not build a house again, all your beams have given away, rafters of the ridge decayed, mind to the unconditioned gone, exhaustion of craving has it reached.(Dhp - 153, 154)
