Toxic Red Tide Poisons California's Sea Life

A toxic algae bloom is sickening and killing dolphins, sea lions, and other marine mammals along the Southern California coast.
The algae produces a neurotoxin that causes brain damage, seizures, and death in animals that ingest it.
Rescue centers are overwhelmed with hundreds of afflicted animals in need of care.
The algae bloom may be exacerbated by climate change and pollution from human activities.
Although the toxin does not pose a direct threat to humans, people are advised to exercise caution around distressed marine animals on shore.
