sustainable cities
definition: Urban environmentalism is at least as old as environmentalism outside of the cities. The origins of urban planning in squalid industrial cities, the rise and decline of the Green Bans in Australia during the 1970s, and the contemporary Environmental Justice Movement in the United States are examples of urban environmental action that challenges environmentalists to rethink notions of the environment, environmentalism, and how we construct boundaries and define cities and nature.
