James McWilliams is the author of Just Food: Where Locavores Get It Wrong and How We Can Truly Eat Responsibly. He argues that being a "locavore" will not help feed the world's population. James does not eat meat, believing that our reliance on land-based protein sources like cattle, is not energy efficient and is the cause of air, land and water pollution. Read about James' arguments in Newsweek.
Part two of this segment will run in next week's show.
