If you’ve been told that “scientists disagree with cetacean captivity”, please know that this assertion is being drawn from a small handful of papers written by a small group that does not represent the entire cetacean science community.
These papers are also designed to market sea sanctuaries as a solution to the welfare issues they claim exists - but they do not acknowledge the significant conflict of interest that exists as Lori Marino gains a decent salary from the Whale Sanctuary Project.
Dr. Jason Bruck wrote a great summary of this - and links to papers and videos:
These are the many papers now challenging Marino review papers (that have no data to back their claims- Lori does not collect data for herself. She misrepresents what other studies say to fit her narrative).
Her paper: https://whalesanctuaryproject.org/wp-content/uploads/Chronic-stress-captive-orcas-Marino-et-al-2020.pdf
Her paper: https://pubmed.ncbi.nlm.nih.gov/34534428/

Hence there are no data to back up her claims and there is quite a bit of literature pointing out that not only are marine mammals starting to outlive their wild counterparts dramatically.

But that they actively anticipate participating in training sessions.

And that not allowing calving has negative welfare implications for the whole group…especially older animals.

Finally, not one but two peer reviewed papers have outlined how GFAS sanctuaries can be detrimental to the welfare of cetaceans.

As for the conservation implications of losing these animals- where do you think we ground truth and test new technologies to help protect wild animals?
Finally here is an in-depth systematic takedown of Marino’s last peer reviewed paper.
