Rising sea levels around South Florida are probably the most important issue facing our megalopolis right now. To counter the deluge— literally and metaphorically speaking—and to respond to consumers’ demand for environmentally sensitive enterprises, developers are employing smart, new construction methods in big and small ways, from innovative HVAC systems to passive cooling methods and various ways of reusing water. Miami Beach is even beginning to elevate its streets. Of course, the green initiatives happening so far only represent a drop in the bucket of what is really needed to save South Florida.
