Smokestacks remove toxins from indoor spaces and have facilitated urban life ever since people transitioned to living in permanent settlements. They travel the world on ships and trains as populations grow and spread, and with the advent of the industrial revolution, larger chimneys proliferated in the city skyline. Modern infrastructure has brought these concrete behemoths out of the city, with power plants dotting the rural landscape. Their smokestacks protrude into the air, repetitive vertical shapes starkly disrupting the horizon and contrasting with the softer shapes of alfalfa and hay bales. Yet no matter how far removed they are from population centers, the smokestacks which do such a good job removing pollutants from inside cannot help but expel them into the atmosphere. How can we change our behavior or improve our technology to find a balance between generating the energy and industry needed to support our society without irrevocably polluting our fragile environment?
