The typical American uses 150 gallons of water a day, vs. 23 gallons for someone in China. Consider the impact on the water supply when more people in developing nations begin living Western lifestyles. In India alone, water usage is expected to rise by nearly 100% over the next 20 years. Expanding populations will also swell demand for agricultural water some 42% by 2030. The hope? Grow more with less water by applying genetically modified seeds, drip irrigation, and other technologies.
