In the third volume of the uTOpia series, dozens of imaginative Torontonians think big and small about sustainability. From suggestions for changes to our transit system and more mixed-use neighbourhoods to a tongue-in-cheek proposal for a painted line around the city and a short comic book about Toronto in the year 2057, GreenTOpia challenges the city and its residents to rethink what it means to be green in a metropolis, and how to take their love of the city one green step further. Other pieces include an interview with Mayor David Miller and a breakdown of the ecological impact of our morning coffee. GreenTOpia features photos, maps and a 56 page green directory of resources, organizations, incentives and programs promoting sustainability in the GTA.
