Regarding environmental knowledge, they prefer plastic bags to carry their purchases because they have no cost. Regarding the environmental impact, they mention that they do know, but have no other option, receiving 6 to 10 bags per purchase that are disposed of for the disposal of garbage. Finally, for the tendency to change, they prefer that the establishments stop providing the bags free of charge, so as not to contaminate, preferring that reusable bags be delivered, and they are willing to pay up to 5 cents per bag. Finally, policies are required to guide consumers to the use of single-use plastic bags.
