Scientists are working to create "superfoods" that can resist pests,
provide more nutrients, and produce higher yields. But the long-term
impact on human health and other life is unknown at best, and many
small farmers and traditional communities are feeling the squeeze from
the corporate drive for "GMOs."
British protests against genetically modified crops demonstrate the fierce controversy over the continued development of such produce, which many environmentalists say may threaten human and environmental health, writes agriculture expert Ben Block.
