Discarded: Which is a better method of agriculture?

This issue moved to another topic and can now be found here

I don't think this really belongs under Health, I'm going to put it somewhere in Environment.

fine by me

Monoculture (growing only one crop on a big farm) is favored by business types because it's more efficient. Polyculture is favored by environmentalists because it's considered more sustainable (less susceptible to disease, better for soil, more biodiversity or something). There could be a worthwhile debate here.
