Increasing urbanization, the huge carbon impact of conventionally grown produce, climate change and the resulting rise in food prices has prompted many people to look for other solutions to feed our growing cities. Entrepreneurs are getting in on the action too: French startup Agricool proposes urban agriculture done hydroponically, out of recycled shipping containers they are calling "cooltainers", to produce food that is "super-local with zero pesticide, zero preservative, zero GMO". The founders of Agricool hope to use their innovative system to grow crops more quickly - using less space and water - to bring affordable, tasty fruits and vegetables to urban centers.
