If we were to really reduce the carbon footprint of human beings, we need to remove all barbershops and praise being bald.
Everyone gets a hair clipper so they can become bald at home. No more energy spent on dyeing, perm or hair drying.
The real bald people are happier since they become ordinary people again. Bald billionaires no longer need to waste tons of money seeking a cure for baldness. Instead, they follow Jeff Bezos.
Baldness becomes the norm. F starts shaving his pubic hair.
