Californians rank the drought as their number-one environmental concern, according to a new statewide survey. The poll by the Public Policy Institute of California (PPIC) found three out of four residents favor mandatory curbs on water use. “They want the local district to do something -- mandatory reductions -- and they want the state government to do something,” said Mark Baldassare, PPIC president and CEO. “They recognize that it is a problem and the most important issue.”
