Hold on there, Mr. Doomsday. We could still turn it around. All it would take is something like MERS to be the next Spanish Flu, and the resulting population decrease would probably go a long way to arresting our environmental impact. There's also the possibility of a supervolcano wiping out large swaths of humanity. Go look up "the year without a spring" on Wikipedia for more.

But who is most likely to be wiped out in those scenarios? Not the wealthiest who are doing the most ecological damage. Never mind the problems of strictly finite resources. To solve these problems humanely, one would have to reduce birth rates and increase standards of living while simultaneously reducing or eliminating reliance on finite resources. And I live in Mississippi and let me tell ya, from here it looks like the willfully ignorant west just assumes they can bulldoze their way through this to dominance without changing a thing. From here it looks like we're doomed by our own willful ignorance.

The rich are below average intelligence and cannot enable themselves. The middle class were actually the enemy of the world, being the middle management scarf binge enabler mediocrity of the 1%. The rich are panicking and hording now because they cast out their fatty feeders and now fear starvation. Since they can't feed each other, and wont, and the poor want to see them all dead, they're doomed. Humans are not. Nature favors numbers, not novelty.

Everyone calm down and read 'collapse' by Jared Diamond.
A very interesting analysis of various societies that have collapsed.

You want to know what the future looks like? Look at the UK during the famine. The poor parts of the world will be exporting food while their population starves, the rich parts will explain that it's their own damn fault for breeding to much and generally being stupid and foreign.

And as for billions of people moving around, it just looks that way because we don't like to shoot unarmed people trying to cross national borders anymore. I think attitudes will change.

Black carbon emissions from biomass and fossil fuels in rural India
http://www-ramanathan.ucsd.edu/files/pr178.pdf

"About 3 billion human beings in developing countries, who subsist on a daily income of less than a day (IEA, 2007) rely on solid biomass fuels for cooking and space heat- ing, contributing to about 25 % of the global emissions of BC and about 50 % of the anthropogenic emissions of BC (Bond et al., 2007). "

The difference with black carbon is that it hangs around, it doesn't dissipate. The particulates have a much more intense local heating effect than, say, your Los Angeles or Houston traffic jam. There's so much BC being shot into the air in India that it could change the monsoon season. Since we're only now figuring out the role of black carbon and biomass on climate change, it's hard to know how any of this stuff is going to unfold. I'm not nearly as freaked out by it as I used to be, but as usual the poorest billions will suffer the most.

Or will they? Maybe Dyson is right and all thos Indians will move to Greenland in 60 years.
