the other day i ran out of garbage bags but i had 800 plastic grocery bags stashed so i decided to use them instead. but, i’m pretty sure they don’t break down, so i wasn’t sure what the best thing was to do… and then i got to thinking, i bet regular garbage bags don’t break down either, also, why not? that’s absurd! but maybe they do!? does anyone know if garbage bags breakdown in landfills? if not what a shame. big shame, biiiig shame.
