Similar in diagram to our own neural cells, our cities will house mega-populations in superstructures interconnected by a vast network of underground tunnels. Through which resources such as food will be transported, information and energy shared. Our concentrated way of living will relieve the earth of its burden to grow our food by constructing our own farms within the mega-structures of our cities. Farm land will be given back. Resources will be more conveniently shared by our proximity to each other. Our cities will be located throughout the world, like outposts, beanstalks to the sky, living among the wild life. We will allow the earth to self-sustain as we sustain ourselves in our cities.
