WE NEED TO DESIGN FOR HUMAN BEHAVIOUR IF WE'RE EVER TO GET RID OF SINGLE-USE PLASTICS

Summary from the TLDR Design newsletter

Consumer motivation for environmentally friendly behavior is high, but we shouldn't ignore people's tendency to prefer convenience, even when it has tragic consequences. While you can't control what people do with packaging once it leaves your premises, you can still influence them by considering behavioral psychology in packaging design.
