Christopher Preston is an environmental philosopher and author, we found him when an excerpt from his book The Synthetic Age about how animals are evolving to use the growing levels of electric light present at night, we had to get him on the show.

We get into human scale versus geological scale problem, the case of interference in natural selection, the varying weights of obligation to do better to the planet across humanity, and failure of awareness-building.

We also talk about getting involved in dark sky and efficiency regulation, banning the wallpack, and the question of who and how to judge what’s best in lighting for all of us.
