What you described is still human centric. Nature has survived several extinction level events and I’m sure it will survive more.

If humanity changes the current environment enough, then it will no longer be the once ideal environment to that continues to sustain humanity indefinitely.

Going on a tangent, a lot of environmentalists have a marketing problem.

Nature will die with 100% certainty. That is a verified fact due to the coming life-cycle changes of our sun. Nothing will survive that.

Only humans have a chance to save "nature" by bringing life along to the stars. Not sure if we will be able to pull it off, but I see no other option.

Sure! On the other hand, if we kill ourselves off before that happens, for example by making the planet unlivable for humans, then that chance is also gone. Getting to that level of technological advancement is a marathon, not a sprint.
