Which bag should you use?

You've filled up your cart and made it to the front of the grocery line when you're confronted with yet another choice: what kind of bag should you use? It might seem obvious that plastic is bad for the environment, and that a paper bag or a cotton tote would be the better option. But is that really true? Luka Seamus Wright and Imogen Ellen Napper explore the environmental impact of each material. [Directed by JodyPrody, narrated by Bethany Cutmore-Scott].
