After hearing how traces of plastic are now being found in hearts that are being examined in autopsies, Cal plays a conversation with a man who has devoted his future to combatting the problem. After working at Adidas for 26 years, Eric Leidtke pivoted to start the Unless Collection, a company that makes shoes, socks and all kinds of clothing out of plants, not plastics. In fact, the Unless Collection's shoes, The Degenerate, can be thrown in a hole in your backyard after they're worn out and they'll biodegrade without leaving behind a trace of pollution. Scientists predict that by 2050, the oceans will have more plastic in them than fish by tonnage. It's important that everyone knows about the work being done by Unless Collection. So, please, spread the word!
