While this strip shows modern pollution makers. The medieval industries were even worse polluters. There were no controls and all waste went back into the environment. They seemed to have no conception of the poisons and toxins they were putting into the soil and their waters. Also they were much more inefficient back then too. The big, big difference with today’s pollution is that is more concentrated an refined. Also the sheer amount of pollution would boggle the Medieval mind. But many modern industries are doing better, realizing that people have to live here too. And are cleaning up their “act”.
