How will China get enough to eat? More than 1.3 billion people live in the world’s most populous nation, and another 100 million will join them by 2030. China is already a net food importer, and people are eating more meat, putting further demands on land used to grow food. Meanwhile, climate change could cut yields of crucial crops—rice, wheat, and corn—by 13 percent over the next 35 years. Mindful of these trends, China’s government spends more than any other on research into genetically modified crops. It’s searching for varieties with higher yields and resistance to pests, disease, drought, and heat. The results are showing up in the nation’s hundreds of plant biotech labs.
