My roommate and I have started to put a list up on the fridge titled “Things we threw out this month”, tallying up the stuff we let go off. It’s not a judgement, it’s just a record. But damn it if, since that list has been up there, I haven’t found myself buying less, worrying I’d fill up the columns and have proof of my own complicity in waste.
In that spirit, I’ve added a registry of air travel to this website. It’s almost certainly an ethical security blanket for myself, but it might be useful to you, too. You can check it out here.
