The San Francisco Board of Supervisors president is developing a bill limiting the sale of bottled water on city property to reduce bottle waste.

Board of Supervisors President David Chiu said, "Every 27 hours Americans consume enough bottled water to circle the entire equator with plastic bottles stacked end to end. We have to do better."

At events around the city a coalition supported area parks going bottle-free. Parks responsive to public support including Mount Rainier, Golden Gate National Recreation Area, Yosemite and Independence National Historic Park, according to a news release from Boston-based Corporate Accountability International.

At least 14 parks nationally have phased out bottled water, according to the group.
