This week we're talking about microplastics.

The average person eats at least 50,000 microplastics a year, and inhales a similar amount. Microplastics have been found in every part of our digestive tract, and are deleterious to the liver and gut. There is good news, however: researchers at Penn State are working on eco-friendly and biodegradable substitutes. They're made from squid teeth.
