“Climate issues won’t end humanity, X will instead”
Or even
“Climate issues will end humanity”
That just sounds like the 21st century version of “memento mori”. We’ve decided a long time ago that that was not a good credo. So, I like to live by “we’re not dead yet”. The odds were against humanity existing at all, but we’re here anyways. So no matter the odds, there’s always a chance we’ll continue existing.
