Make a crazy eco-rule that affects thousands and the mainstream media finds critics – who said it doesn’t go far enough. San Francisco Mayor Gavin Newsome banned city departments from purchasing bottled water, even for water coolers. But that wasn’t good enough for Greenpeace Energy Policy analyst Samantha Rogers.Rogers told CNN’s “American Morning” fill-in host Rob Marciano she wanted to see the mayor do more than just ban plastic bottles, but to sign a plan championed by global warming doomsayers that would force the city to have more than 50 percent of its energy come from renewable resources by the year 2017.Marciano joined in and suggested to viewers that “one way everybody could save the environment” is drink tap water instead of bottled water.The city, built near the volatile San Andreas Fault, is susceptible to earthquakes and has witnessed major earthquakes, notably in 1906 and 1989. Another earthquake could damage the city’s volatile public works structure that delivers tap water to the city’s 700,000-plus population. CNN’s coverage skipped that little possibility.
