Can agriculture be natural?

I left the food intensive feeling confused, but also enlightened. Our food system is extremely complicated and I am not sure exactly what the ideal solution would be.  One thing that came up very often on the trip was what natural meant to each person that we visited. Each person had very different definitions of what natural was.  When we visited Full Belly farm and started talking about what natural meant I realized that nothing about our food system is natural. The whole idea of agricultural is unnatural, organic or not. I really enjoyed visiting the Regenerative Design Institute in Point Reyes. The Regenerative Design Institute is a permaculture center. James, who lives at the center, gave us a tour and we discussed a lot of things about permaculture. The more we talked about it the more I liked the ideas. I think having things like an edible forest garden are a great way to produce food in a more natural and sustainable way. An edible forest garden really utilizes all the space to produce food.  There are a lot of other permaculture concepts that seems more sustainable and mimic natural cycles. I think trying to mimic those cycles in nature will help make less of an impact on the land.
