Hellooo, dear listener! In this fourth and last part of the episode, I finish telling you the story of a group of Italian researchers who, for the first ever, find plastics in human placentas of healthy women. Listening to this episode, you'll find out how bad is global plastic pollution, and how dangerous plastics are to living thing in general, and to humans and human fetuses in particular. And there's also a brief interview to Dr. Ragusa, the leading investigator of this research! Aaand there's a also funny+unsettling fake commercial too... Ciao!
