Audio long-read: How harmful are microplastics?
Scientists are trying to figure out whether these pervasive plastic specks are dangerous.
Wherever they look \u2013 from the bottom of oceans to the top of mountains \u2013 researchers are uncovering tiny specks of plastic, known as microplastics.
Scientists are trying to understand the potential impacts of ingesting these pervasive plastics but early results are ambiguous, as some experiments might not reflect the diversity of microplastics that exist in the real world.
This is an audio version of our feature: Microplastics are everywhere \u2014 but are they harmful?
