Perhaps you envision yourself as environmentally conscious. You recycle, drive a hybrid, compost and even use a water reclamation system. Don't get me wrong, that's great, but there are a number of local folks who are taking it to the next level. Not only do they educate others on sustainable living, but they themselves have become catalysts for change. Meet six local leaders: Mark Fisher from the Cincinnati Zoo, Dan Korman from Park and Vine, Jess Linz from Queen City Bike, Brewster Rhoads from Paddlefest, Jim & Ellen Schenk from Imago Earth Center and Valerie Taylor, who runs the Cincinnati Locavore blog.
