In this video below, Kathy Freston talks about the virtues of going vegan and the environmental and health benefits that result.

Even if you're not ready for a full vegan diet, Freston suggests going meatless for one day per week. If every American did so for one year, she explains, it would be the equivalent of taking eight million cars off the road.
