Environmentalism is, finally, a death wish. It is an intensely personal claim that the believer is not worthy of life. It must end in suicide if its adherent is faithful. Environmentalism ritualizes ignorance. It is most appropriate that its adherents celebrate their religion by living, if for only an hour, in total darkness.
For the living, turn on every light, honk every horn, brighten every corner, fill every second of that bleak hour with hope and joy and light.
