This podcast examines the role of water in food production, irrigation for agriculture, and the new industry of aquaculture. The research has shown that enormous quantities of water are used in the production of food, particularly animal products. Irrigation depends on freshwater sources greatly, especially groundwater. Also, aquaculture can pollute water with chemicals and waste. Nevertheless, there are policies that have been taken and that can be taken in the future to preserve water and use it wisely.
