For instance, oldgrowth forest in parts of North America is not considered a renewable resource despite the fact that trees may return even after an area has been logged. The time it would take for an oldgrowth forest to be restored can be over a hundred years, rendering it essentially a nonrenewable resource. The fact that renewable resources have the potential to be selfperpetuating or regenerative also does not preclude the possibility that they can be exploited or depleted to extinction. For instance, the great auk, a flightless sea bird found in the north Atlantic, once numbered in the millions but was exploited to extinction by the middle of the nineteenth century.
