Can returning crops to their wild states help feed the world?

This article talks about how returning crops to their wild states might help feed the world in the near future. They discuss how experimentally breeding with these crops has made them lose some of their important properties. A scientist in the article suggested a way that fixes weaknesses that have sprung up by accident in the process of traditional crop breeding over the course of thousands of years. The scientist suggested that we replace those lost properties by isolating them from related plants, or using precision methods to repair the faulty genes. The one problem with this is, by definition, these methods of replacing the lost properties is genetically modifying the plants. That is a problem because just being categorized with the word genetically modified usually has a negative connotation, and people are not going to like it, even though it's not really genetically modifying these crops.

This article relates to our curriculum because learning about GMO's, and if they could feed a growing population was a key part of our unit about genetic engineering, and we even had a debate about it.
