Malls have lost a lot of their popularity in consumer culture which has caused many malls to close down. This leaves huge swathes of land unoccupied in towns and cities that can be repurposed from something destructive to the environment to something that respects it.
Well, if a mall hasn’t already closed, it can consider one of the new iterations of the contemporary mall. Communities and city planners have gotten creative, using abandoned mall spaces for schools, government offices, medical clinics, casinos, wedding venues, call centers and churches. And while some malls are being torn down and housing or completely new retail buildings are being built, it is much more economically savvy (and green) to reuse the existing infrastructures.
How about an urban farm? While streams and other natural features have been brought back from being buried under concrete in some situations where malls are getting makeovers (along with adding putting greens, dog parks and other outdoor activities), a few enterprising souls have taken a look at the great natural light (many malls were built with skylights), good access to public transportation, and central locations. And thinking green.
