In many places, demand for water exceeds supply. Approximately 97% of the world's water is salty and undrinkable; 3% of the water is freshwater, but 2% of all the water is frozen in glaciers and polar ice caps. 73% of freshwater use (80%+ in the U.S.) is agricultural, 21% is industrial, and 6% is domestic. On irrigated land in California, one ton of corn uses 200 gallons of water, one ton of rice requires 4,000,000 gallons of water, one ton of grain-fed meat requires 1,000,000-2,000,000 gallons of water. One ton of steel requires 60,000 gallons of water. For domestic use, Be waterwise.
