I wonder if experiential diversity has increased. Surely the decrease of biodiversity is painful for mother earth, but perhaps there is greater variation in the the experiences of all living organisms.

EDIT: Just a runaway thought: why is biodiversity important? If we are optimizing for the general well-being of humans and living beings on earth (which is the frame of reference I am using), then extinction of a species while increasing experiential diversity seems worthwhile.

In addition, the extinction of a species is only sad to those who remember. Many cultures have merged in history to become nations we see today, but nobody misses the oh-so-glory days of a specific Northern German tribe in BC 500.

As to the beauty we experience from diversity of species (seeing them, interacting with them), I would much rather enjoy technological experiences over that natural experience.

Perhaps this makes it sound all too all-or-nothing-esque, but it seems that there is a general assumption that increased biodiversity is good beyond measure.
