I don't remember the numbers (in species/yr) offhand, but I've read
arguements (e.g. by S J Gould) that claim that we are *now* in the midst of
the one of greatest (if not in fact _the_ greatest) of mass extinctions of
all time.

If I recall right, the numbers work out to ~1 species/100,000 increase in
human population.
