I went to this distant future world, and what I found was eccentric. Luminescent homes on platforms! Below them were deep mists. And every five seconds cool moist air would rush up. To my surprise, I found there were tunnels in the platform's base pushing air in and out. But I learned that these were no tunnels. They were pores of giant plants to clean the air and light the living houses! We could start working towards this by combining strong plants or trees with frames to shape them.
