I’ll read through that article but since the article discusses a general dynamic it’s fair to reason about whether and to what extent that dynamic is in play in a given particular context . It seems that the point of ‘contention’ here is food scarcity and competition for Tuna, and it seems the orca are losing the point and either the humans have acquired the role of apex predator in that particular part of the ocean or at the least the orcas’ services as such are no longer required.

It may be that reading this article will provide the wherewithal to answer this question but perhaps there’s someone here who understands the particulars and can shed some light.
