[Question] Non-human centric view of existence

Talking with a friend recently on this, and we started to get to this topic:

Zooming out and viewing existence from nature/​all creature point of view—why must human/​humanity live/​continue forever?

We admit we are self-preservation focused, and the answer to this question eventually probably does not change much on what we do. Maybe just some more attention to suffering risks rather than death.

I wonder what people’s thoughts are on this, as I was a bit caught off guard for this question.

(I also encourage professional conversations that are focused on the topic/​question itself.)
