The population is expected to climb to 9 billion within the next 50 years. As a result, crucial natural resources will dwindle. This article looks at four that will be much harder to come by in the future.

The phenomenon has been dubbed the "global food crisis of 2008" - but some are beginning to refer to it as the "perpetual food crisis."
