Green roofs are pretty great because they assist in flood prevention and can grow crops. Indeed, green roofs are growing in popularity around the world because they are great for cleaning air and cooling cities too! It’s almost as if many urban problems can be solved by converting unused space into usable green environs.
In Chicago green roofs are being planted throughout the city and are proving to be very beneficial. The New Republic decided to reveal the mini-paradises that these small roofs can create.
By 2050, 2.5 billion more people are projected to leave the countryside for the city; in the United States alone, urban land will more than double by 2100. Faced with what scientists call “the urban heat island effect,” cities around the world are encouraging the development of roof gardens. These blankets of wildflowers, grasses, and sometimes even vegetables reduce water runoff, absorb carbon dioxide, and lower temperatures. Chicago is home to the world’s largest rooftop farm: The two acres of land atop a soap factory supply a million pounds of vegetables a year.
