While some may scoff at the idea of farming in the city, the truth is that a lot of food could be grown within city limits, if more businesses and apartment dwellers embraced the concept of rooftop gardening. In most given cities, there are tens of thousands of square miles of flat rooftop capable of being converted to growing space. In the biggest cities, that space is much greater still.
It was recently estimated by students of the University of Toronto that the city could produce $1.7billion worth of fruits, vegetables, and legume atop the many flat roofs. Better yet, in the efforts to grow such bounty, the city would greatly reduce what is commonly referred to as ‘urban heating’. That is the effect caused by the flat, black rooftops absorbing massive amounts of heat from the sun’s rays and increasing the temperature experienced by the city dwellers. Not only could the excessive heat in a city be reduced, but plants can do double duty. They, of course, can produce a hunger quenching harvest, but they also clean the air. If each of the rooftops in Toronto were to install a garden, the result would be reduced smog, reduced cooling costs in the summer months, and drastically lower need for food import.
It is assumed that as more people realize the benefits and embrace urban agriculture, it will become a major phenomenon. Green living is not just for the country folk anymore.
