All fair points. My earlier reply was incomplete because there are 2 factors at play, similar to the
two arrows parable.
Factor 1: Personal bias. Hard to deny.
Factor 2: Honest and stark realities
I like to use the term
Holocene Mass Extinction since it will, over the course of a mere few hundred years of recent and forthcoming history, combine all human-caused ecological destructions such as deforestation, ocean acidification, temperature rises, pollution of air/water/soil, any nuclear warfare, etc. under a single geologic umbrella.
Denying such things is not merely positive thinking, but a loss of touch with reality. Yet often this is what people do in the name of mental health as a survival strategy. Albeit, not one sustainable for the population.
Combine the two factors and it's hard to take a black-and-white viewpoint. At best, it might add intensity to fundamental questions about the purpose of life and what we are supposed to do in this situation.
