Can you explain how visiting SeaWorld or any other places with captive orcas drives a demand for wild captures?
A park existing and needing animals over time will logically require new wild additions. Bottlenose dolphins will be the only captive cetacean left if not (since so many of them were caught initially and their captive breeding program is very robust.)
There’s nothing stopping any of these places from trying to acquire more wild-caught cetaceans. It’s not illegal, there’s just a wall of rules to comply with and a lot of the public is opposed. Public opposition is most of the reason any of it has stopped or changed; it’s unlikely any US facility will be able to import orcas ever again, not because it’s strictly forbidden but because it’d be PR hell. But as proven by the beluga import debacle, that doesn’t stop other species from being subject to the problem. Until these facilities aren’t trying to use “cetacean” as a selling point, they’re still liable to drive wild captures. Also keep in mind the trades with overseas facilities for captive offspring – which then may be replaced at the foreign facility w/wild caught animals.
That also says nothing of the example SW/etc sets for other places: by showing how profitable and attractive it is to have these animals, it’s perpetuated both the industry and the problem.
For orcas specifically, Seaworld has spent 50+ years showing everyone how amazing it was to have them as a tourist draw. Even though the company’s trying to distance itself from the concept now, it doesn’t change that they’ve been rolling boulders down a steep hill for decades – and hey, they’re still rolling. One of their bigger, recent boulders is the mess they’ve made at Loro Parque – who, is now free to delve into wild-caught animals itself.
