Climate change, acid rain, the ozone layer, over-fishing, polluted rivers… the list of environmental problems can seem daunting – and then when solutions appear, it seems there’s another problem just waiting to pop up behind it! What seems to be needed is a concerted effort to reform the foundations of our cities and towns into more sustainable entities that work in harmony with our planet: Fortunately, this is just what several grassroots environmental movements are trying to do. Between the Transition Towns, the Sustainable Neighborhoods, and Agenda 21, cities all over the world (and all over Belgium!) are taking concrete steps to become more sustainable and to cut off environmental problems before they even start.
