不幸的是,全国美国农业土地举办了多种多样的多样性,少数商品庄稼主导了农业景观和经济。我们国家农业并不总是如此生态,但大多数农业政策都激励了对非人食品作物的态度不成比例的致力于服务饲养,果糖和乙醇。As a result, pragmatic farmers who have simply been responding to the economic imperatives laid before them, are now vulnerable to the long-term systemic effects of fossil fuel-intensive, non-diversified farming, i.e., flooding and/or drought, soil loss and degradation, dependence on imported nitrogen fertilizers and expensive chemical inputs, limited markets, and poor diets. This puts our nation’s food security at risk, not to mention our long-term ecological stability.
