We knew that government subsidies to Big Agribusiness were screwed up, but we didn’t know how badly screwed up until we saw this chart from the Physicians Committee for Responsible Medicine (by way of TreeHugger).

Originally published in 2007 by Physicians Committee for Responsible Medicine (PCRM) in Good Medicine Magazine  to outline the committee’s concern about the impending farm bill. The graphic recently resurfaced in food security circles and found its way to the Economix Blog @ The New York Times .
