Some say one of the biggest positive effects we can have on our environment is bring the food production closer to the people. This helps the environment in many ways by reducing the transportation cost of moving the food to its destination. Estimates show New York City could produce enough food to substance its entire population with 16 green house skyscrapers spread around the city. And all the greenhouse skyscrapers could be ran off solar power and water collected from yearly rain fall. Sure this is a big undertaking but we have already started to see the progression to urban farming.
