Plastic in our blood? That’s a problem.

Our planet is filled with plastic. On average, we produce 430 million tons every year, most of which is used only for a short period of time and then discarded. But plastic isn’t just in the environment: it’s now in our bodies. Microplastics have been found in our bloodstreams, lungs, and other organs, and we’re only recently beginning to understand how this affects our health. In this episode, host Samantha Laine Perfas, cell biologist Don Ingber, environmental health scientist Mary Johnson, and nanomaterial researcher Philip Demokritou discuss our destructive relationship with plastic.
