What will it take to downsize the American meat habit?
I was a strict vegetarian for 10 years. Now I'm a sort of sometimes-meat-avoider: my wife and I keep a meatless kitchen but eat whatever when someone serves it to us and sometimes when we're out. As I've written before, the virtuous identity marker "vegetarian" is less important to me than it used to be. But I still think eating way less meat is the single biggest bit of lifestyle "greening" most Americans could do.
The U.S. Department of Agriculture's dietary guidelines restrict their official purview to nutrition; they don't address the other considerations that go into food choices. But last week, AP reported that this year's update to the USDA guidlines might include a focus on environmental sustainability—specifically, as a reason to eat less meat.
