844 animals and plants are known to have gone extinct in the last 500 years, ranging from the dodo to the Golden Toad in Costa Rica.

The dodo went extinct about 350 years ago. Some soft tissue still exists so it will be cloned and brought back to life someday. Does anyone know the last plant or animal to really go extinct?

Earth's wild days are almost over. No plant or animal alive today will go extinct unless we choose. And no large meteor will strike Earth again.

Are the earth's wild days over?

How long before the earth's wobble evens out? That wild polar tilt every year is gradualy decreasing, which could be responsible in part for the very gradual warming of northern hemispere, but I haven't seen any theories on when it will become insignificant to the point where seasonal changes are barely noticable.

There was the passenger pigeon in the US sometime in the 1800's. I am skeptical of any serious plantlife going extinct. But I have no idea what may or may not have gone belly up since.
