For great many species today, fitness means the ability to get along in a world in which humankind has become the most powerful evolutionary force.

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.

Another thing cooking is, or can be, is a way to honor the things we're eating, the animals and plants and fungi that have been sacrificed to gratify our needs and desires, as well as the places and the people that produced them. Cooks have their ways of saying grace too... Cooking something thoughtfully is a way to celebrate both that species and our relation to it.

But human deciding what to eat without professional guidance - something they have been doing with notable success since coming down out of the trees - is seriously unprofitable if you're a food company, a definite career loser if you're nutritionist, and just plain boring if you're a newspaper editor or reporter.

Studies show that organically grown crops produce more of the things (ascorbic acid, lycopenes, resveratrol, flavonols in general, etc) that our bodies need and also have less toxic residue. Science is still catching up with this. J. Agric. Food. Chem. Vol. 51, no. 5, 2003.

A lawn is nature under totalitarian rule.

Ecology also teaches that all life on earth can be viewed as a competition among species for the solar energy captured by green plants and stored in the form of complex carbon molecules. A food chain is a system for passing those calories on to species that lack the pant's unique ability to synthesize them from sunlight.
