Radical slow food guru Joel Salatin is not popular with vegetarians. New Age wisdom has held that modern man had to transcend meat, the only sustainable future calling for us to cut out the middle beast and narrow our source of nutrition to the more efficient vegetable kingdom. Except it turns out that agriculture is no more sustainable than mining. Here’s the lesson I gleaned from Joel Salatin’s lecture last Saturday. Nature wants to grow grass not grain. The greatest environmental disaster to befall Earth was mankind’s development of wheat. Calling humans omnivores pretends we can eat anything, when in reality outside of meat we’re limited to the product of tillage, for the most part requiring irrigation and fertilizer. A sustainable biosphere calls for perennials cycled through their consumers, ruminant herbivores. As omni as we wanna be, we’re not herbivores.
