The bill is backed by State Assemblyman Richard Bloom (D-Santa Monica), marine biologist and orca expert Dr. Naomi Rose and former SeaWorld trainer Samantha Berg.
"As a former Marine Mammal Trainer at SeaWorld, I saw firsthand how orcas suffer in captivity," Berg said in a statement. "No amount of toys, larger tanks, better veterinary care or love and attention from their trainers will ever come close to simulating the richness of their lives in the ocean. We cannot meet their needs in captivity."
The news follows SeaWorld's third-quarter earnings report on Thursday, which revealed lower-than-expected numbers and led to a stock market tumble. The company has been suffering since the release of the 2013 film "Blackfish," which led to public concerns over the company's treatment of its orcas.
