I think using waste oils as fuel makes sense. We do waste a huge amount of vegetable oil in this country and using that as a fuel source strikes me as fine.

The best farming systems are ones where animals and plants are put into a synergistic relationship.

The interesting thing I learned was that if you're really concerned about your health, the best decisions for your health turn out to be the best decisions for the farmers and the best decisions for the environment-and that there is no contradiction there.

For a product to carry a health claim on its package, it must first have a package, so right off the bat it's more likely to be processed rather than a whole food.
