Paris just wrapped up its Week of Sustainable Development, a showcase of the City’s myriad efforts to promote green thinking, from renewable energy to pedestrian and cyclist-friendly policies. Paris has also made a big push to green its already-green spaces: its parks and gardens. With 82 parks designated for “ecological management” and about 60 community gardens, Parisians are growing their own food and enjoying life in open spaces that are not only more sustainable, but more natural.
