U.N. Report Says Climate Change Could Mean Less Food

The Primary: A major United Nations report on climate change concludes that not only is human activity leading to climate change, but such change could reduce global food supply if left unchecked. The report states that resources are being exploited at “unprecedented rates.”

Who? What? Why?: Increased flooding, heat spikes, natural disasters and droughts are caused by change in climate, which, in turn, can disrupt or destroy food resources.

The Baseline: More than 10 percent of the world's population is currently undernourished, according to the New York Times. Climate change could exacerbate the problem.
