World is finite, human demand is not

The Finite World - "In particular, today, as in 2007-2008, the primary driving force behind rising commodity prices isn’t demand from the United States. It’s demand from China and other emerging economies. As more and more people in formerly poor nations are entering the global middle class, they’re beginning to drive cars and eat meat, placing growing pressure on world oil and food supplies.

And those supplies aren’t keeping pace. Conventional oil production has been flat for four years; in that sense, at least, peak oil has arrived. True, alternative sources, like oil from Canada’s tar sands, have continued to grow. But these alternative sources come at relatively high cost, both monetary and environmental.

Also, over the past year, extreme weather — especially severe heat and drought in some important agricultural regions — played an important role in driving up food prices. And, yes, there’s every reason to believe that climate change is making such weather episodes more common."
