Vertical farms have become a growing strategy to ease food insecurity in dense cities, and now an architect wants to take one to new heights. MIT’s Carlo Ratti has proposed a 51-story skyscraper in China’s technology hub of Shenzhen, with greenery encasing its entire shell. The farm would sit between two sets of windows in the building’s “double-skin facade,” allowing sunlight to reach both the plants and the interior. The tower would also house office space, a supermarket and a food court, and could produce enough greens, tomatoes and berries for 40,000 people.
