I tend to agree with the other posters. Why extinction? Why not massive population decline?

Very, very few if any legitimate biologists would support this point. The group of biologists that supported this view were called group selectionists. They argued that individuals do things for the benefit of the group. Group selectionists have gone the way of the dodo. Most biologists that even recognize group selection would regard it as a very weak force, much weaker than genic selection. Species do not have goals. From a biological perspective individuals do not reproduce for the benefit of their species, but rather for themselves (or more appropriately: for the benefit of their genes).

I'm skeptical about your comments regarding planetary self-preservation. Do you have references for the "many scientists"? (I'm honestly curious). Nature is dealing with us? Is nature a conscious entity?

Reasonable questions to which I don't have good answers. Maybe humans aren't capable of thinking about such large populations or such an extensive resource depletion as we have today. I don't know.
