Cheap food is an illusion. There is no such thing as cheap food. The real cost of the food is paid somewhere. And if it isn't paid at the cash register, it's charged to the environment or to the public purse in the form of subsidies. And it's charged to your health.

A natural historian is somebody who looks at something in terms of its relationship to the rest of the natural world. You look at things ecologically. When you see a cow on a feedlot, you don't just see a cow; you see a cow that is eating certain food. You follow that food and that food takes you back to a corn field.

The ninety-nine cent price of a fast-food hamburger simply doesn't take account of that meal's true cost--to soil, oil, public health, the public purse, etc., costs which are never charged directly to the consumer but, indirectly and invisibly, to the taxpayer (in the form of subsidies), the health care system (in the form of food-borne illnesses and obesity), and the environment (in the form of pollution), not to mention the welfare of the workers in the feedlot and the slaughterhouse and the welfare of the animals themselves.

We need to create incentives for our ranchers and farmers to manage their lands to maximize carbon sequestration.

It's very important to get out, to do reporting. It's also really interesting. I come at it as a journalist, and I think that's helped me, and I come at it as someone who sees nature wherever he looks, and that helps.

The green thumb is equable in the face of nature's uncertainties; he moves among her mysteries without feeling the need for control or explanations or once-and-for-all solutions. To garden well is to be happy amid the babble of the objective world, untroubled by its refusal to be reduced by our ideas of it, its indomitable rankness.

If you care about the animals, actually, organic might not be the best answer because now we have organic feedlots, organic factory farms. If you care about the environment - pesticides, especially - organic is the answer.
