Sea Stars of Washington State Facing Toxic Threats:

A fresh wave of research finds that sea stars in the Puget Sound of Washington State are having a tough time surviving, thanks to microplastics and pesticides. The sunflower sea stars are seeing a mass die-off, with toxic substances affecting the growth of the young ones, posing a major roadblock for their population rebound.

The Mini Troublemakers:

Microplastics and pesticides are the latest suspects in the decline of the sea stars. Microfibers, a type of microplastic that is commonly found in clothing and textiles, are being ingested by the sea stars. These microfibers not only are toxic, but also transport harmful chemicals. Even the pesticide Imidacloprid, well-known for its devastating effects on bee colonies, is seen to prevent the growth of the stomachs in sea stars leading to their death.

The Domino Effect:

The downfall of the sea stars has a ripple effect. Without enough sunflower sea stars, sea urchins go unchecked, turning the kelp forests - sources of shelter for young fish - into barren wastelands.

Hope on the Horizon:

Luckily, help might be on the way. The state senate in Oregon is contemplating a bill that would mandate microplastic filters in new washing machines sold in the state. Additionally, the federal government has proposed listing the sunflower sea star as a threatened species under the Endangered Species Act. This action would trigger a ban on the release of the pesticide in the region. So, fingers crossed for a brighter future for the sunflower sea stars!
