You don't have to look deep into your hearts to know that keeping these animals in tanks just feels wrong. I think the caption on the picture says it all really.
In a new study, nearly a year in the making, former SeaWorld trainers Jeffrey Ventre, MD and John Jett, Ph.D, take us deep behind the scenes of Marine parks and their ability to provide environments adequate for keeping killer whales alive in captivity.
Drs Ventre and Jett introduce us to detailed observations and strong statistical calculations that add up to an abundance of evidence that captivity kills orcas, usually at a young age… and that stresses, social tensions and poor health are chronic issues in marine park facilities.
