Michael Pollan

On Oct. 23 ABC's "Good Morning America" aired back-to-back segments promoting climate change and, strangely enough, slamming hamburgers. First, George Stephanopoulos worried that Americans were becoming too complacent about global warming and discussed possible climate solutions with "Superfreakonomics" author Stephen Dubner. Dubner suggested choosing a kangaroo burger over a beef burger as a possible solution. Then Stephanopoulos interviewed Michael Pollan, author of "The Omnivore's Dilemma," and discussed the carbon footprint left behind by a McDonald's quarter-pounder with cheese.

Pollan said that "you're eating oil" when you're eating a burger: "You need oil to make the fertilizer to grow the corn. You need petroleum to make the pesticides to grow the corn. You need oil to move it all around the country."

Factoring in production, processing, and shipment, Pollan claimed that a quarter-pounder cheeseburger amounts to 26 ounces of oil. "What it tells you is that the carbon footprint of that burger is really big," said Pollan. "The result is a product that takes a huge environmental toll and obviously takes a health toll as well."

Mother knows best?  Or journalist does?

ABC's "Nightline" seems to think so when it comes to nutrition advice. The May 8 broadcast featured health tips from a writer with no scientific background encouraging viewers to only eat food their mother would recognize.

Michael Pollan, a long-time opponent of "agribusiness" - the food industry - was featured in a segment on his new book, "In Defense of Food: And Eater's Manifesto." Pollan advocates a return to an all-organic diet and offers tips for healthy eating.

Pollan praised "the authority of mom" and lamented that "the holders of culture when it comes to food (mothers) have been undermined by both the scientists and the food marketers."
