The Chicago Tribune reported Thursday on IPCC predictions that the impending climate crisis will have intense ramifications on water and food — reducing the availability and increasing the costs of each. This is particularly disturbing, because these commodities are already in short supply in the parts of the world that are most vulnerable to the effects of warming. There are already millions of people without access to sanitary water for drinking and cleaning, and food prices are already spiking and causing trouble for aid organizations like the UN’s World Food Program. History has taught us that a scarcity of necessary resources leads to violent conflict. Droughts are largely responsible for sparking violence in Darfur, and Ban Ki-Moon himself has implicated global warming in that case. This is another in a long list of reasons why governments should take immediate action to quell the climate crisis. After all, the price of bread has brought down more than one regime.
