FOOD PRODUCTION - HYDROPONICS
http://www.econeighbors.org/econeighbors/Econeighbors_Science_Barge.htmlModern farming feeds billions, but is the world’s largest consumer of both land and water, the primary source of water pollution, and accounts for 15% of global greenhouse gas emissions.1
More than half the world’s population now lives in cities, and “the average vegetable eaten has traveled several thousand miles just to get on the plate.” 2
The Science Barge grows food in the city with no carbon emissions, no net water consumption, and no waste stream. Asked how much food could be grown this way, NY Sunworks responded: Studies suggest there could be enough rooftop space in New York City to grow all of our fresh vegetables.
