Mate it's all pie in the sky, by the time the human race feel the water at their feet it still wont matter, we can do nothing as a collective because we just aren't capable.
Again, too many people using too many resources, it isn't going to change and the planet will remove us from it, it's the animals I feel sympathy for not us.
So all the gnashing of teeth does is make what little time we have on here as miserable as possible, we really are cunts and it's so easy to project false virtues knowing fuck all is ever going to get done without billions of people just disappearing off the planet.
