Why are people against sea pens ?
I’ve been reviewing the arguments regarding the use of sea pens for cetaceans (Killer whales), and I know this group has some reservations, so I would really like to understand your perspective better. Despite sea pens often being presented as a more humane alternative to concrete tanks—offering natural seawater, currents, and more space—what are the specific reasons you remain against them? For instance, are you concerned that these enclosures still limit the animals' natural, wide-ranging behaviors, or do you feel that issues like exposure to water pollution, high tourist traffic, noise disruption, and the risk of extreme weather damage still make them too detrimental to welfare? I’m interested in whether you view them as a step forward or just another form of confinement that keeps these intelligent animals in a "life sentence" rather than allowing for true freedom.
