A sobering article by Gwynne Dyer (author of Climate Wars), as he examines the phenomenon of food riots and whether they are likely to become more prevalent in the future. The food supply will likely become tighter due to factors ranging from extreme weather and groundwater depletion to increased demand for meat. Climate change will strain the food supply even further, resulting in higher prices and increased pressure on governments to try to solve the problem. Dyer believes that more strife is likely in the future unless climate change can somehow be brought under control.
