Comparisons are sometimes made between recent extinctions (approximately since the Industrial Revolution) and the Pleistocene extinction near the end of the last glacial period. The latter is exemplified by the extinction of large herbivores such as the woolly mammoth and the carnivores that preyed on them. Humans of this era actively hunted the mammoth and the mastodon, but it is not known if this hunting was the cause of the subsequent massive ecological changes, widespread extinctions and climate changes.
