While extinctions are always multi-faceted, the extermination of some species can be almost directly linked to the insatiable appetites of modern humans. Read on to discover a few of the animals we have lost to our unthinking exploitation.
- Dodo - Raphus cucullatus

Dodo (Raphus cucullatus).
Encyclopædia Britannica, Inc./Christine McCabe“Dead as a dodo.” Yep. These flightless, ground-nesting birds were once bountiful on the island of Mauritius in the Indian Ocean. Larger than turkeys, dodos weighed about 23 kg (about 50 pounds) and had blue-gray plumage and a large head. With no natural predators, the birds were unfazed by the Portuguese sailors that discovered them around 1507. These and subsequent sailors quickly decimated the dodo population as an easy source of fresh meat for their voyages. The later introduction of monkeys, pigs, and rats to the island proved catastrophic to the languishing birds as the mammals feasted on their vulnerable eggs. The last dodo was killed in 1681. Sadly, very few scientific descriptions or museum specimens exist.
- Steller’s Sea Cow - Hydrodamalis gigas

The Steller's sea cow (Hydrodamalis gigas), extinct since the 18th century, fed on kelp growing near the shore.
Encyclopædia Britannica, Inc.Discovered in 1741 by German naturalist Georg W. Steller, Steller’s sea cows once inhabited the near-shore areas of the Komandor Islands in the Bering Sea. Much larger than present-day manatees and dugongs, Steller’s sea cows reached a length of 9–10 meters (over 30 feet) and weighed around 10 metric tons (22,000 pounds). These massive, docile animals floated at the surface of the coastal waters but unfortunately had little ability to submerge. This made them easy targets for the harpoons of Russian seal hunters, who prized them as a source of meat on long sea journeys. Killing was often wasteful and the species was exterminated by 1768, less than 30 years after it was first discovered. No preserved specimens exist today.
- Passenger Pigeon - Ectopistes migratorius

Bill Reasons—The National Audubon Society Collection/Photo ResearchersOnce famed for its massive migratory flocks that would darken the sky for days, the passenger pigeon was hunted to extinction in the early 1900s. Billions of these gregarious birds once inhabited eastern North America and were similar in appearance to the mourning dove. As American settlers pressed westward, passenger pigeons were slaughtered by the million yearly for their meat and shipped by railway carloads for sale in city markets. Hunters often raided their nesting grounds and annihilated entire colonies in a single breeding season. From 1870 the decline of the species became precipitous and some unsuccessful attempts were made to breed the birds in captivity. The last known passenger pigeon, named Martha, died on Sept. 1, 1914, in the Cincinnati Zoo in Ohio.
- Eurasian Aurochs - Bos primigenius primigenius

AdstockRFOne of the ancestors of modern cattle, the Eurasian aurochs was a large, wild ox that once ranged across the steppes of Europe, Siberia, and Central Asia. Standing 1.8 meters (6 feet) high at the shoulder with substantial, forward-curving horns, Eurasian aurochs were known for their aggressive temperaments and were battled for sport in ancient Roman arenas. As a game animal, Eurasian aurochs were hunted excessively and gradually became locally extinct in many areas throughout their range. By the 13th century, populations had declined so much that the right to hunt them was restricted to nobles and royal households in eastern Europe. In 1564, gamekeepers recorded only 38 animals in a royal survey and the last known Eurasian aurochs, a female, died in Poland in 1627 from natural causes.
- Great Auk - Pinguinus impennis

From The Birds of America, from Drawings Made in the United States, Vol. VII, by John James Audubon, 1844The great auk was a flightless seabird that bred in colonies on rocky islands in the North Atlantic, namely St. Kilda, the Faroe Islands, Iceland, and Funk Island off Newfoundland. The birds were approximately 75 cm (30 inches) long and had short wings which were used for underwater swimming. Utterly defenseless, great auks were killed by rapacious hunters for food and bait, particularly during the early 1800s. Enormous numbers were captured by sailors, who often drove the birds up planks and slaughtered them on their way into the hold of a vessel. The last known specimens were killed in June 1844 at Eldey island, Iceland, for a museum collection.
- Woolly Mammoth - Mammuthus primigenius

These massive animals died out around 7,500 years ago, after the end of the last Ice Age. While climate change definitely played a significant role in their extinction, recent studies suggest that humans may have also been a driving force in their demise, or at least the final cause. Extensive hunting and the stresses of a warming climate are a lethal combination, and it seems even the mighty mammoth could not withstand the human appetite in a changing world.
