"Single-use" plastic is often used for a long time, longer than "eco" alternatives like paper bags that simply don't do the job well enough to be reused.
Glass and paper are horrible alternatives (for the environment) if not recycled properly (and they aren't, like plastic).
Paper grocery bags give off gas when they rot, whereas the (smaller) amount of energy in a plastic grocery bag is carbon locked in a controlled landfill. I think there’s a strong argument for plastic bags being more environmentally friendly.
