The way skeptics see it, Dickson Despommier has a lot of explaining
to do: He’s got big plans for the future of farming. By 2050, the
planet will have to feed three billion additional mouths, and
traditional farms, which threaten food security by deforestation, the
use of fossil fuels and ecosystem destruction, will not be able to
hack it. Dr. Despommier, an environmental health scientist at
Columbia University, believes the answer lies in the vertical farm, a
glass-walled structure that can be designed as tall as a typical
skyscraper, and can be located inside city bounds or around city
limits.
