Ooh look at you Canadians and your environmentally friendly attitudeThat stereotype doesn’t run true for everyone tbh, it’s more of a thing where bagged milk is also available but not the absolute standard, as oppose to it being rare everywhere else.
Personally the thing i like about it is it takes up less space in fridge, i can fit about 4 in space of 2 cartons. Also, freezing it is easier
But ultimately it’s down to waste and other bs tht i don’t agree with, cause human waste is minuscule to the amount multinationals waste plastic
