In the Curiosity Stream documentaries, I discovered several segments that talked about the concept of megacities. We often think we can build cities horizontally forever, but the truth is that the Earth’s surface is finite. As our population grows, it would make sense to build cities vertically to accommodate our increasing numbers. Megacities are essentially super sized skyscrapers and can house tens of thousands of residents. Some megacities could be built on land, on artificial islands in the middle of the ocean, be 3D printed, or have plants and jungles growing from their walls. I am thinking of featuring a megacity in my new superhero series that could house a quarter million residents. It will be the last of its kind.
