Debunking the Holocene 'Sixth Mass Extinction': 250,000 years from now at current rate

An article today titled "Here’s Every Single Animal That Became Extinct In The Last 100 Years (PHOTOS)" lists and shows photos of a total of only 127 animals that have become extinct over the past 100 years. 

There are a total of about 1,263,186 animal species documented on Earth, a count that increases by about 10,000 per year from new discoveries:

Subtracting insect species, for which it is difficult to determine extinctions, gives a total currently known non-insect animal species of ~313,386. 

Thus, the 127 animal extinctions over the past 100 years amounts to 0.04% of the currently known [and increasing] non-insect animal species. 

At this rate of extinctions of 0.04% per century [which by the list below is not accelerating], it would take ~250,000 years to cause the "sixth mass extinction" that the usual alarmist outlets are crying wolf about, far longer than the onset of the next ice age [which would truly produce a mass extinction]. The fact is mass extinctions have naturally occurred 5 times before, well over 99.9% of the living species to have ever inhabited the Earth are now extinct, and it's not your fault.
