While I fully support transitioning away from fossil fuels, I hope students appreciate the challenge it will be to do so. As such, I’d like to challenge every student to go an entire 24-hour day living without anything, product or service, that is made from petroleum. To get started, go without anything plastic, such as electronic equipment, most clothing (polyester), even bicycles as they use grease (in the rotating parts), plastic peddles, handgrips, etc. No use of student desks, either, as they are coated with a plastic resin. Exception: plastic medical devices (insulin syringes/pumps, stints, etc) are exempt. Also go without electricity or building heat (steam boilers use natural gas/coal). I suggested this challenge years ago for inclusion in your Perspectives Course due to the Professor’s anti-petroleum bias, so perhaps students have already completed this challenge.
