It seems to me that the greens are plotting the extinction of the human race, by banning fur coats, fossil fuels to heat homes, and nuclear power to heat as well. The ethanol situation was a stroke of brilliance, cutting off our food supply and fossil fuels in one swift stroke.
The greens are rabid anti-capitalists and anti-humans. The anti-capitalist group seeks to destroy the U.S. economy in any manner possible. The anti-humans want to wipe out humans and any contributions they have made since the dawn of time. The anti-capitalists ally themselves with socialists, communists and "environmentalists" that use government regulation as a means of doing political and economic damage. The anti-humans engage in eco-terrorism e.g. ALF.
Using food crops e.g. corn and soy as feedstock for ethanol is just stupid. It is causing major food price increases across the board.
