Exposure to microplastic makes animals want to eat it more Over multiple generations, small nematode worms began preferring microplastic-contaminated food over cleaner options, which could have consequences for ecosystem health

Why would an animal choose to eat microplastics? And what does that mean for us? Learn about the worms with an acquired taste.

Thanks to Song Lin Chua and Lee (Mick) Demi for taking the time to chat with me about this fascinating research.
