In the 90-minute BBC special, wildlife biologist Liz Bonnin travelled the world to investigate the plastic crisis up close. She spoke to researchers, marine biologists, campaigners and innovators in an attempt to understand the implications of the epidemic and figure out if it’s possible to turn back the plastic tide before it’s too late. By anchoring the narrative in Liz’s personal journey, audiences experience both the tragedy and the hope of the plastic story through a more intimate and emotional lens.
