Experts ring alarm bells at the first ever United Nations Ocean Conference: Our oceans are in danger. One of the key culprits: Microbeads.

The tiny plastics commonly found in cosmetics products are a nightmare for marine ecosystems. Just one bottle of face wash contains hundreds of thousands of microbeads destined for our oceans, where fish often mistake them for food particles.

But research shows that microbeads are even more dangerous than we knew.

A team of Australian researchers have recently shown that pollutants that accumulate on the surface of microbeads are absorbed by the fish that ingest them. Meaning pollutants leached from microbeads may well be ending up on our dinner plates.
