These must be the same kinds of people who'd kill a human being to save an animal in its natural habitat. People who put everything else (animals, trees, the earth) above themselves just so they can make themselves feel better. This is not very different from what many villains from cartoons/anime/movies have tried to do, talking about "how humans are unworthy of this or that", so they decide to destroy the world or simply try to destroy every human on the planet. They're so deluded with hatred for their own species that they can't find any other solution other than inciting a genocide. Not only that, but they probably let one little tiny fact fly right past them; the earth will survive even if the human race will go on a rampage! Survival is the earth's middle name, so no matter what we humans do to it, it'll be fine by itself. It has everything it needs to survive, so killing ourselves won't make a damn bit of difference.

In the end, these people are definitely insane. No one is going to voluntarily help them go through with this "movement", which in fact will most likely be torn apart by the media itself. The only thing they offer is the destruction of freewill and our overall freedom because they're whining about the earth.

In the words of Greg Gutfeld (Red Eye on FoxNews), "You sir, are worse than hitler."
