Plastic is everywhere—it’s in our food containers, keyboards, glasses, even our toothbrushes. It’s lightweight, versatile, and so cheap that we often forget how much it permeates our lives. A new book dives into the plastic crisis—answering the questions of who is being harmed, who is to blame and what we must do now to create a more just and livable world for everyone. We speak with author Erica Cirino.
