By week three, Arthur is piously carrying a KeepCup to work himself and says half his office is, too, with some colleagues refusing to buy rounds for those without reusable cups. He’s also turning the lights off more at our flat ‘because of the turtles’ and chiding the neighbours for ramming our recycling bins with plastic, as well as ‘more Amazon parcels’ and glass. We are, I think, doing quite well. Lush is particularly good for cosmetics, so we’ve been able to swap normal bathroom stuff for non-plastic alternatives. Its ‘hard’ toothpaste, which looks like mint imperials and foams into normal-ish stuff when you chew and brush, also comes with mouthwash ‘mints’ for afterwards — these do come in containers made of plastic, but there’s much less of it than your usual toothpaste tube or mouthwash bottle.
