Adaptation

If you’re going to have sustainable agriculture, it has to be adapted locally. Local adaptation means that you observe in the economic landscape the same processes that you find in healthy natural landscapes: You must have diversity. You must have both plants and animals. You must waste nothing. You must obey the law of return — that is, you must return to the ground all the nutrients that you take from it. You must protect the soil from erosion at all times. You must make maximum use of sunlight. In those circumstances, you may leave the crops and animals pretty much to fend for themselves against diseases. The farm will have some disease, but it won’t have epidemics. If you look at a healthy forest, for instance, you see some prematurely dead trees, but not massive numbers of them.
