Environmental analyst Lester Brown has made a lifetime career of tracking declining supplies of global resources. He is the founder of the Earth Policy Institute and author of the book Plan B 4.0 Mobilizing to Save Civilization, both of which provide massive data sets on the precipitous drop in key natural resources as well as urgent policy recommendations for addressing them.
In today's podcast, Chris and Lester discuss the global depletion themes that concern Lester most greatly, including population growth, water usage, limits to food production, and climate changes. In many of these areas, the picture painted by the data is alarming. Our future choices are quickly being limited to when these constraints will limit our way of life, not if.
