There has been a documentary called Deadly Brew: The Human Toll of Ethanol provided by Bloomberg Television recently. I haven't seen it but a short review at AutoblogGreen with a video clip is available. The commentary sounds interesting and the post raises a few points for debate as well.
I like the idea of ethanol but the political tinkering with it in the U.S. has made it an exercise in pork spending, which, ironically, raises the price of pork and other foods. We shall see what happens with ethanol but I'm not optimistic.
