USA TIERE HUND
Three dogs play at Fort Funston Park in San Francisco, Tuesday, Feb. 21, 2006. As San Francisco city officials strive for creative ways to keep all trash out of landfills by 2020, they're hoping to harness the power of dog doo. Experts in alternative energy sources are now going to the dogs in search of fuel for methane digesters that could fuel stoves, heaters or power lights. (KEYSTONE/AP Photo/Paul Sakuma)
