“In the case of agriculture and drought, there’s a clear and accessible action most citizens can take: reducing or, ideally, eliminating the consumption of animal products. Changing one’s diet to replace 50 percent of animal products with edible plants like legumes, nuts and tubers results in a 30 percent reduction in an individual’s food-related water footprint. Going vegetarian, a better option in many respects, reduces that water footprint by almost 60 percent.”
