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.
