Catastrophe-- Part 5 of a series

Lester Brown draws our attention to three factors contributing to a possible catastrophe in world food supply. See Journey to Planet Earth, PBS.
1. World population continues to grow, even with some population planning bright spots in Bangladesh, etc.
2. As income rises in places like China and India, the demand for animal products grows that literally takes bread out of the mouths of the remaining poor.
3. Conversion of food crops (especially corn) to ethanol.
This adds up to higher food prices that we are already seeing, which is particularly ominous for the poor of the world. We are already seeing some failed nation states where inadequate and more costly food is part of the problem—Chad, Somalia, Afghanistan, Sudan, D.R. Congo, and Haiti.
