because the mega-corp owned agricultural industry is so great…all city dwellers should just forget how to grow food because “someone has it covered”. i mean its working so well. people are healthier and happier than ever…certainly aren’t any “food deserts” because the corps got it covered man! just wait for the monsanto truck to show up and feed everyone. or…dare to think out side the box and see that solving “food deserts” might just include tearing up some concrete and planting a few food plants instead of bazillions of square kilometers of manicured grass and generi-bushes.
