This extinction event really got moving when? A hundred years ago? Two hundred at most? Geologically speaking, if the history of the planet lasted a day, man's mission to exterminate life would be barely a fraction of a second in length, would it not?
No biological entity could ever come close to humankind's destructiveness. We're attacking life on every front. Seriously, you're underestimating the effect of our greed. And it's science-fiction hippy-bullshit if you can predict a greener human 100 years down the road. That'll never come to be whilst capitalism is king.
Of course, I hope you're right and I'm wrong. I just have no faith in humans pulling their heads out their asses whilst people like Donald Trump (and the rest) are in the world.
Also...
Imagine if the impoverished half of the world demand the trappings of wealth that the rich half have enjoyed for so long. As their nations eventually stop warring / their nations' economies begin to grow. If the developing world was no more and all nations could be regarded as being developed.
Is it racist to say they must not be allowed to develop their economies? (Is that what Western governments have been plotting against for so long?)
Because we're fucked if every African wants a fridge, a laptop, a telly and a car. And a nice house to live in.
Maybe trickle down economics will save the planet in the end? ;) ;) ;) (I personally hate the concept, ordinarily.)
I'm hardly predicting a greener future- merely pointing out that our destructive capabilities are still outmatched by the Earth's destructive powers. I- and extinction researchers of all stripes- have taken into account the insane speed at which we spread extinction. (We actually started arpund 10k years ago). The numbers still don't even approach the big extinctions. In fact, the speed at which we're moving is the main reason why we're causing these extinctions- if human pressures had been applied slower, far more species could have adapted.
As for whether your claim is racist- well, you were the one who brought that into the conversation, so I think that's one you probably have the answer to already.
