n a permanent extension of a 2007 law, San Francisco has made it illegal for the City to buy or distribute plastic water bottles. Bottled water contributes to massive amounts of litter and plastic waste all over the world. San Francisco has an aggressive plan to achieve zero net waste by 2020. In late 2013, Inhabitat reported that San Francisco’s Board of Supervisors appeared ready to enact one of the strictest bans on bottled water in the nation. Days ago, the proposal became law, and plastic water bottles smaller than 21 ounces will no longer be allowed on city property starting Oct. 1, 2014.
