Oh for Pete's Sake - Harvard Hometown Plans Coercive Taxes, Veganism to Stop Climate 'Emergency'. Congestion pricing to reduce car travel. Elimination of curbside parking. A carbon tax "of some kind," not to mention taxes on plastic and paper bags. Advocating vegetarianism and veganism, complete with "Meatless or Vegan Mondays." Those are just some of the proposals put forth by the Cambridge Climate Congress, an entity created in May 2009 to respond to the "climate emergency" plaguing the Massachusetts city.
