It becomes quite obvious when someone doesn't seriously want to engage with a user in good faith when they don't follow the chain of discussion, such reviewing citations provided by other users in discussions based off of said citations and instead reflexively coming to their own baseless conclusions based off of only knowing a portion of the information in the whole discussion.

This is to say go listen to Attenborough's speech for like 20 minutes and if, somehow, you still can't hear the answer to your question then I'll point where it's relevantly discussed, assuming you're actually asking in good faith.
