I think George Carlin had the best take regarding climat change if I'm not mistaken and it was something along the lines of, "no the planet is not dying we are the planet will be fine after us" and I have to agree have you seen the movies in which humanity dies and the planet it's just natural taking over everywhere, that what's going to happend, we will fuck things up untill we die from our own stupidity and then the planet will heal herself!
We always have done that and due to use who knows how many species are already extinct! Thing is after we ar out nature will come back and other species will rise up from the ashes!
