We live - for how much longer we will live I do not know - in both a modern plenticidal age and a postmodern neo-plenitude age.
We humans are trying hard as we can to kill off all other lifeforms, killing the golden goose, so we can have this earthly golden egg all to ourselves.
So we are plenticidal : killing off Nature's plenitude, thinking that draining her gene pool is a good thing , just as we used to think draining wetlands was a good thing too.
