Of the various strategies to implement sustainable agricultural practices that will still help to feed a growing world, which ones seem the most promising, and why? What's the best way to encourage farmers to stop traditional practices of "clearing land" for farming and have them work with nature while still producing crops? How about regenerative farming; should this be left primarily to the big companies that buy these crops, or should governmental regulations or incentives be used? Are Genetically Modified Organisms (GMOs) a valid way to increase crop yield and quality, or should there be limits on how much science should be tinkering with "natural" foods?
