I would highly recommend the recent Freakonomics Radio series about whaling. It's Episodes 549-551 and the bonus episode from 2023-08-06. If you're firmly against killing any living creature (or at least sentient creatures), I highly doubt it will change your mind (and I don't think that it should or that it tries to), but I also think it is really fascinating learning about the history of the whaling industry and hearing the perspective of a modern whaler in the bonus episode. Putting aside the obvious ethical issues with killing sentient creatures, it's interesting to consider things like whether there's a sustainable level of whaling, what a sustainable quota would look like, and how much we're in competition with certain whale species for harvesting fish as food for our own species. I personally appreciated how unbiased Freakonomics tried to be in their discussion of the topic.
