Look at the average American diet: ice cream, butter, cheese, whole milk, all this fat. People don't realize how much of this stuff you get by the end of the day. High blood pressure is from all this high-fat eating.

I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.

Topsoil is a place of digestion. It sucks and chews things into smaller pieces. When it's hungry, it turns grey and stony; when it's thirsty, it opens thousands of cracked lips. Subsoil is more skeletal: it doesn't digest.
