We have food deserts in our cities. We know that the distance you live from a supplier of fresh produce is one of the best predictors of your health.

A cow out on grass is just an incredible thing to behold... Cows and other ruminants can do things we just can't do. They have the most highly evolved digestive organ on the planet, called the rumen.
