The 4 day work week (or more) will save the planet and environment

I feel thats all I really need to say here. I work for the government and I'm never working on Fridays. I don't need the extra money, I'm not broke and I have things to do for 8 hours a day anyway, why do I need to waste and extra day of gas driving to work? And the same goes for most people. There is nothing wrong with a 4 day work week, and I'm sure it will help with mental health and the environment.
