But when you consider 400 have been discovered in the last 25 years one could presume an equal or even higher amount will be discovered every quarter century with technolgy advancing, so we can add 8,000 new species over the next 5 centuries staying at the same discovery rate.

Using the frog numbers and adjusting for undiscovered mammals, 80/13,570 have become extinct over the past 5 centuries or 1/2 of 1 percent of mammals.

I'd say the world should be proud not alarmed.....
