First they came for the Wild Auroch.
And you said nothing.
Then they came for the Woodland Bison.
And you said nothing.
Then they saw off the multiple millions of Passenger Pigeon.
The Bastard Gum’s gone, the St Helena Ebony Tree, the Lago Yojoa Palm.
And still you said nothing.
They came for the Japanese River Otter.
And you said nothing.
Then they came for the Northern White Rhino.
And you said nothing.
They even got the Indefatigable Galapagos Mouse after they finished off Darwin’s Rice Rat.
Now they’re coming for the Elephants, Polar Bears and me the last Pangolin and hundreds of other creatures, some of which we don’t even know exist yet.

This is a link to Wikipedia’s list of extinct animals by region. There you can also find links to extinction lists of plants.

The vast majority of extinctions, though, are thought to be undocumented.

Estimates show that the extinction rate now is running a very large amount above normal background levels. Some, with good evidence, claim we are in the middle of a mass extinction event.
