Wow! Reading these comments is really scary and depressing. - almost as depressing as reading the comments on breitbart.com. Why do so many people believe so many irrational things with such tenacity? It is almost enough to say "bring on climate change".  Perhaps evolution over the next few million or billion years will create another species on the earth capable of intelligently living within the restraints of its environment after we are gone. There are billions upon billions of other stars in the universe and many will have developed life forms some of which will have done better than humans and will continue to exist and thrive long after we are gone.
