Why do evolutionists protect endagered species???

[Jackalope]

Lots of contradictions here:
How does "natural selection" give us a duty to save endangered species?

I didn't make that claim. I did make the claim that in some cases, it is in our self-interest to do so (e.g. if the food chain collapses, it puts our future in jeopardy).

Is self-interest just a cover-up term for emotions? It seems to be so.

No, self-interest is self-interest, in terms of our potential for future survivability of our species.

How does evolution give justification for what is and isn't destructive behavior?

It doesn't claim to.
