Greens need to rethink their longstanding opposition to genetically modified crops, writes Jason Pontin. The changing climate is making it harder for small farmers to stay in business, and GMO crops might be the only way to feed the world's growing population. "With luck, we may be able to increase yields sufficiently to feed the nine billion people who will be alive in 2050 and design crops that can tolerate heat, drought, and new patterns of plant disease," Pontin writes.
