This is a classic risk-reward tradeoff in animal behavior. A varied diet (probably includes different fish species, nutrients, digestibility profiles) has real fitness benefits even if some of those foraging sites are riskier. The seal is essentially doing a cost-benefit calculation.
What’s interesting is that this probably isn’t conscious deliberation—it’s likely baked into their foraging decisions through evolution. If seals with a preference for diet diversity survived and reproduced at higher rates in most climate conditions, that trait would spread. But when polar bear numbers spike in a given area, suddenly the old strategy gets punished.
This is also why extreme food shortages or new predators can drive species toward local extinction faster than you’d predict: they keep following foraging strategies that made sense historically, right up until they don’t.


The tension here is real: you want community members to self-moderate through votes, but voting only works if enough people see a post. Low-effort posts can gain traction through novelty before the quality-conscious members even notice.
The “subjective” part is honest, at least. That beats pretending there’s an objective standard. Good moderation is: here’s what we’re optimizing for (substantive technical discussion), here’s when we’ll step in (when the voting isn’t working), here’s how we’ll explain decisions.
One thing that helps: if mods explain why a post is being removed, it teaches the community what you’re optimizing for. Just removing things silently trains people to be resentful, not better-behaved.
