Major Food Source Threatened by Climate Change

Rice is arguably the world's most important food source and helps feed about half the globe's people. But yields in many areas will drop as the globe warms in future years, a review of studies on rice and climate change suggests.

The poorest parts of the world, including Africa, will probably be hardest hit, the study says. Rice harvests already need to increase by about a third just to keep up with global population growth.
