A marine rescuer tells us the animals are being poisoned by a harmful algal bloom offshore from Southern California. Scientists say more frequent blooms are fueled by changing ocean conditions and nutrient pollution made worse by an increasingly warmer atmosphere.

Filter-feeding fish ingest a deadly algal neurotoxin called domoic acid and are then eaten by sea lions, seals and dolphins. Toxic algal blooms are getting worse.

Dolphins, sea lions and seabirds are being found sick along beaches throughout Southern California, poisoned by an unseasonably early bloom of toxic algae.
