Michael Pollan is a professor of science and environmental journalism at University of California at Berkeley.
In an open letter to the next president, author Michael Pollan writes about the waning health of America's food systems — and warns that "the era of cheap and abundant food appears to be drawing to a close."
The future president's food policies, says Pollan, will have a large impact on a wide range of issues, including national security, climate change, energy independence and health care.
Pollan is the author of The Omnivore's Dilemma: A Natural History Of Four Meals and In Defense OF Food: An Eater's Manifesto.
