Water usage is probably my biggest. Living in a high desert, my wife and MIL see no problem with filling one side of the sink with hot soapy water to wash a few dishes because “that’s just how I’ve always done it”, to watering the grass and plants for hours. All of this makes me mental.
We had Car2Go in our city, but they went bankrupt because of the tragedy of the commons- got trashed by both terrible drivers and slobs who made every surface sticky… We need a drastically different education and culture first. [might work in japan]
