Food Towers the Farms of the Future?

As the human population continues to grow–some estimates suggest we may be heading for a worldwide total of 11,000,000,000 people, two-thirds more than on Earth today–feeding everyone is going to be a big challenge.


New forms of sustainable farming are needed desperately. Some people propose that part of the solution might be found in giant skyscraper plantations in the cities, such as this 58-story “Skyfarm” envisaged by Gordon Graff at the University of Waterloo in Ontario.
