Eat mostly plants, especially leaves.

One of the most irresponsible things we can do is eat in ignorance, without any awareness of what our eating is doing to the world or to other species.

...A one-pound box of prewashed lettuce contains 80 calories of food energy. According to Cornell ecologist David Pimentel, growing, chilling, washing, packaging, and transporting that box of organic salad to a plate on the East Coast takes more than 4,600 calories of fossil fuel energy, or 57 calories of fossil fuel for every calorie of food.

There's no sacrifice in eating well, there is no sacrifice in pleasure. To the contrary, the best-grown food is actually the tastiest.

...think of agriculture as something the grasses did to people to conquer the trees.

All money for agricultural extension, land grant universities has been toward developing industrial food. Lots of money has been invested toward maximizing yield. If you took even a small amount of that money and put it toward organic research, I don't have any doubts you could match those yields.

Farms produce a lot more than food; they also produce a kind of landscape and a kind of community.
