I can certainly touch on some of them.
Drought-tolerant crops are already being produced, so in areas where water scarcity is an issue, it has a huge environmental impact. The biotech crops we do have—the herbicide-tolerant—have allowed for no-till farming, or conservation tillage, to Mr. Breton's point about greenhouse gas conservation and the fact that we're not driving over the land as many times as we used to in order to control weeds. There are a lot of factors that can be developed right in the genetics of the plant that have tremendous benefits for the environment or health, such as the oils that were mentioned.
