Relentless human-population growth coupled with rising consumption has outpaced the planet’s ability to cope. An article in BBC’s Green Room says we are now in "overshoot" -- our numbers and levels of consumption greater than Earth's capacity to sustain us for the long-term. The writer says we must end world population growth, and then reduce population size in industrialized as well as developing nations.

"The Age of Consequences" report by the Center for Strategic and International Studies (CSIS) in the US, predicts that scarcity of resources may "dictate the terms of international relations" for years to come as rich countries could "go through a 30-year process of kicking away from the lifeboat."

Another report says energy needs in 2030 could rise more than 50% above current levels, mainly due to rapid economic growth in China and India. So who’s going to be kicking who?

The group also called for caps on the energy use of major appliances and a ban on goods that exceed restrictions. Britain’s ruling Labour Party, not surprisingly, has questioned the Tories’ calculations.
