Vertical farms
New York magazine asked four architecture firms to come up with their plans for a deserted block in the heart of Manhattan. One of them designed a vertical farm, a concept that has been publicized since at least 2005. Vertical farms are ambitious projects but would bring sustainable agriculture right into the city, thereby solving a number of environmental problems such as the cost and greenhouse-gas emissions caused by food transportation.
