If you consider that we are currently destroying our eco system that we need to survive and have known for over 50 years that the co2 levels will cause major issues, but nobody really felt the need to act. And when the countries actually sat together and made the Kyoto contracts the USA steped in and fucks up the whole idea. Thanks Bush you little Oil-fucker!
Considering that you could say humanity is fucked and humans are at fault. And if you look at it the people voting are at fault too, falling for company and other proparganda and voting for a government that fucks them even harder.
I would say humanity as we know it won’t exist anymore in 200 years. War, droughts, floods and shit will get us. Even if we would act now the whole planet would need to cooperate. No Chance!
