One year, when their fields were inundated with a would-be plague of grasshoppers, they put chicken coops in their fields so that the chickens could eat the grasshoppers and then they could eat the chickens. ”The goal,” as Hernández put it, ”is always to integrate and manage the equilibrium.” An old-fashioned approach one might say, but a thoroughly sane approach in my view. Whatever the sustainable agriculture movement heralds -- as an alternative to the Green Revolution or to the coming bio-tech or GMO (genetically modified organism) movement -- it reminds us of the sacredness of the full circle of creation and the possibility that, if we try, we can all live in harmony together.
