| (Xinhua) -- San Francisco Mayor Gavin Nesom has issued an executive order prohibiting city departments from buying bottled water so as to protect the environment and save cost, it was reported Saturday. The decision would save taxpayer money and combat global warming, the Los Angeles Times reported, quoting Tony Winnicker, spokesman for the San Francisco Public Utilities Commission. More than 40 million gallons of oil are needed to make the plastic water bottles Americans purchase each year, according to data cited by the mayor when he made the decision earlier this week. City offices must rely on tap water, said the mayor, citing environmental concerns and cost. |
