At least, it is for about 1/4 of the world's mammals:

Nearly a quarter of the world's land mammal species are at risk of extinction, and many others may vanish before they are even known to science, according to a major annual survey of global wildlife.

At least 1,141 of the 5,487 known species of mammal are threatened, with 188 listed in the highest risk "critically endangered" category. One in three marine mammals are also threatened, according to the five year review.

Oh geez.

Why do I keep posting this kind of stuff? Am I sado-masochist? Trying to inflict sadist mental torment on myself and others? Or am I (insanely) brave in my need to stare into so many hearts of darkness? There's no judge qualified to mediate over THAT trial.

Have courage friends. Extinction phases have come and gone in the long history of this resilient earth. But perhaps humanity has never been the witness (or the cause) before. Truly amazing times...
