I'd put that in the Armageddon category. We were talking about massive over-population and the resulting "adjustment." This usually means a massive die-off.
Species don't matter.
They matter to themselves of course, and the mix and numbers of species matter to the perpetuation of life.
Life is consequential to conditions.
As far as we know from our experience: Where matter is favorable, life emerges, where life is favorable, intelligence emerges, where intelligence is favorable, consciousness emerges.
Yes in consequence to conditions, but everything interrelated to the whole, and, in our experience, that includes living things.
It's not difficult to imagine nothing at all exists, or even a soup of particles and forces becoming nothing more.
Anyway, all this is inconsequential on a cosmic scale. In our little village things matter. But just because someone has, say, a domestic issue doesn't mean the rest of the creation cares or depends on it.
