Starfish alarm

It's another blow for biodiversity. Hundreds of starfish have been found dead in British Columbia. Scientists believe a nonnative parasite is to blame. Purple sea stars began washing up on the beach last week north of Vancouver.

Why should we care? It's that web of life thing - sea stars eat mussels and barnacles, making more room in intertidal zones for creatures that support other marine and bird life.
