Did you know? The heat in the upper six miles of the earth’s crust contains 50,000 times much as energy as found in all the world’s oil and gas reserves combined. Despite this abundance, only 10,500 megawatts of geothermal generating capacity have been harnessed worldwide.

Food Situation Highlights Presentation for World on the Edge: How to Prevent Environmental and Economic Collapse
When Will the Food Bubble Burst?
Millions of people around the world are fed by "food bubbles," artificially high levels of food production that could drop suddenly at any moment, triggering food price spikes, inciting civil unrest, and swelling the ranks of the world's hungry. Rising food prices in early 2011 are approaching the 2007-08 price spike that led to a dramatic jump in the number of hungry people around the world. As overpumping depletes aquifers and increasingly extreme weather events destroy crops, it becomes ever more likely that food is the weak link that could bring down our global civilization.
Based on Lester Brown's latest book, World on the Edge: How to Prevent Environmental and Economic Collapse, this presentation highlights just a few of the most urgent threats to our global food supply and the trends that created them.
