Over the next 50 years? Yeah, almost certainly. If the current change continues for the next 50 years, you’re going to have ecosystems changing _dramatically_. Of course, it’s kind of speculative, as you _can’t_ really disentangle the other effects of humanity easily, but if the current trend continues for another 50 years, it’s hard to see how that would not lead to a mass extinction event.

I mean, I think we can say that is _definitely_ not what is happening right now. It is not just doing it on its own. Like, what would the mechanism be?

You sound like you are a person with the certainty I'm confused by. You haven't included any rationale, you are just very sure about things.
