To promote water conservation, the U.S. Environmental Protection Agency kicked off an educational campaign today that features four families competing in reality-TV fashion to see which can save the most water. The “We’re for Water Campaign” campaign began in Los Angeles, where two families will spend the next week competing, and will travel across the country to New York, where two more families will face the same week-long challenge. The EPA says that from 1950 to 2000, the U.S. population nearly doubled but public demand for water more than tripled. It says at least 36 states anticipate local, regional or statewide water shortages by 2013. The EPA says consumers can start saving water with three simple steps: check, twist and replace.
