This episode, hosts David Anderson and Gina Vitale travel back in time to relive three historical moments that were pivotal in the evolution of microplastics. They also bring in C&EN reporter Bri Barbu to discuss how biodegradable plastics, if employed responsibly, may offer a glimmer of hope.

C&EN's Inflection Point, leans on our 100-year archive to trace headline topics in science today back to their disparate and surprising roots. In each episode, we explore three lesser-known moments in science history that ultimately led us to current-day breakthroughs. With help from expert C&EN reporters, this new show examines how discoveries from our past have shaped our present and will change our future.
