I think that the best sustainable use of land is not to try to do better than nature or god, or the universe. We are not smart enough to do better with the land than the land will do, by itself, in a natural way.
We think that we can control the land to suit our needs better, but we are only satisfying our immediate needs at the price of abusing that same land.
Who is to say that using a million acres for soya is better than the forest that was there?
Who is to say that raising a million cows is better than the buffalo that was there before and without fences?
In America, instead of conquering the natives, we should have adopted their way of life and respect nature better. If you use your brain right, it should be easier to hunt/trap as a system of sustenance than farming.
Like they say when men are fishing; The white man looks for fish, the aboriginal looks for ducks (and finds fishes underneath).
>>> “”Milk produced from dairy cows given diets containing soya bean meal is a more sustainable use of land than producing human drink products directly from soya beans, especially when cows are grazed on pastures.””
