Upwards of 3 million people die annually from diarrhea, dysentery, and parasitic diseases -- all for the want of clean water. Meanwhile, each year in the water-rich United States, 2.1 billion gallons of the world's most precious liquid are used, not to water thirsty crops or slake parched throats, but to flush human waste from home toilets to municipal sewers. While harvesting rainwater and recycling graywater are fine strategies, it's time to get to the seat of the problem. We need a Toilet Revolution.

As frequently happens, the solution to this modern problem can be found in the recent past -- and the Third World present. Jeff Conant, author of The Community Guide to Environmental Health, has traveled the world in search of the perfect "waterless toilet." He found it in the Mexican town of Tepotzlan, which boasts hundreds of "non-traditional waterless" eco-loos. In the 1980s, Tepotzlan's innovators got a boost when former UNICEF worker Ron Sawyer settled in to help the locals design a new generation of "eco-san" toilets.
