There’s just so many factors, I never was one to think extinction was necessarily a bad thing for example, but some view it as a huge loss or even as some kind of evil.
I’m sure there’s plenty of species that have been phased out and new ones that adapted into being all throughout history, but we look at it through this simplistic human view and say “we must absolutely do this to preserve or do this to destroy because of XYZ reasons” and given our track record over the past thousand years when it comes to science I have to assume there’s a high chance that we are very wrong in our assumptions.
