10 species of animals, which seeks man
Last Tasmanian wolf - a marsupial mammal with a dog's head - he died in an Australian zoo in 1936. Although for a long time it was thought that for the extinction of a species is responsible some unknown infection that Thylacine allegedly infected by imported dogs in Australia, in fact responsible for the destruction of this species of wolves lies entirely on the person.
Unfortunately, Tasmanian wolves - is not the only animal species that has been completely or partially destroyed by humans. Yes, in the natural world animals are found with a lot of threat to its own existence - here and abrupt climate change, predators, which must also be something to eat, and unexpected epidemic - but the biggest threat to wildlife has always been a man with his undying thirst for murder.
We chose 10 animal species that have been destroyed by man, in order to show what we have lost.
or Tasmanian marsupial wolf, also known as tilatsin, lived in mainland Australia and the island of New Guinea. For the first time it has undergone habitat change after to New Guinea people were transported dingo dog. Recent ousted marsupial wolf from his normal habitat, and nowadays he is "moved" to live on the island of Tasmania.
Local Australian farmers considered it a potential threat to sheep and so mercilessly exterminated wolves, without attaching any importance to where they saw them, and whether they represent a threat to others.
"Many believe that the cruel and unjustified destruction of wolves could not lead to the extinction of a species, and blame it on some unexplored disease that supposedly wiped out the entire population tilatsinov", - said Thomas Prowse from the Australian University of Adelaide. However, scientists have for a long time and thoroughly studied this question using various models, and found that only and exclusively the man behind the extermination of the Tasmanian wolf in the response.
It is believed that the last Thylacine was killed May 13, 1930, and in 1936 in one of Australia Zoo died of old age last Thylacine in captivity.
Year of extinction: 1936
It is believed that this type of mammoths first appeared in Siberia, about 300-250 million years ago and gradually spread to Europe and North America. Dimensions mammoths were not that huge, according to most not too familiar with the history of the people: they were only a little more than modern elephants.
Mammoths lived in groups, which are headed by a senior female, and constantly moved from place to place, as an adult mammoth require about 180 kg of food daily. That - and this is obvious - is not intended to marking time in one place.
Completely woolly mammoth disappeared about 10,000 years ago. And although there are many theories of why they became extinct (the loss of genetic diversity, climate change, outbreak, and so on. D.), Recent studies are increasingly inclined to believe that the final blow to this type of mammoths was caused human hand.
the complete disappearance: 10 000 years ago
Dodo Mauritian dodo or
The Mauritius dodo has long been considered a mythical bird whose existence was completely invented and actually it does not exist in nature. But after a specially arranged to Mauritius expedition discovered the remains of a bird, the society had to accept the fact that there was a bird, and it was the cause of her people began exterminating. Dodo lived in Mauritius for several centuries, it is not fear of their natural enemies, which did not exist on the island. That is why the bird was flightless - she just has nobody was hiding.
First saw the bird in 1598 Dutch sailors, and literally 100 years it has been completely wiped out - tried themselves travelers and animals that were brought to Mauritius colonists. Still, think of yourself, how attractive for sailors had dinner with 20-pound birds, which are considered the closest relatives of modern pigeons.
Year of extinction: presumably 1681
Sea and Steller's sea cow was discovered in 1741 by the expedition of Vitus Bering and received its name in honor of the doctor of the expedition Georg Steller, who was not too lazy to describe the sea cow from all sides, and that his descriptions are still considered to be the most complete.
Steller's sea cow lived off the coast of the Commander Islands, and has not only a low mobility, the huge size and a complete lack of fear of humans, but also delicious meat. The latter was the reason that less than 30 years after its opening, the sea cow was completely destroyed.
Sailors ate its meat, bovine fat used in food and lighting, from the skin were making boats. In a word, we ate everything what could reach. In this case, the capture and killing of sea cows were often unnecessarily cruel and meaningless: "Most hunters simply throwing spears sea cow, and then allowed to float away, hoping that the animal would die and his body will make the shore." Year of extinction: 1768
passenger pigeon before the beginning of the XIX century was one of the most common birds on the ground, its population numbered up to 5 billion individuals. However, this amount is not enough birds to pigeons survived. Lived in what is now the United States and Canada, passenger pigeon have been the subject of active hunting colonists arriving in America.
Reducing the number of pigeons took place more or less smooth pace until about 1870, then in less than 20 years, their number has decreased dramatically and the last just dove in the wild was seen in 1900. In captivity, wandering pigeons lasted right up to 1914, when the zoo of Cincinnati died last bird named Martha.
Year of extinction: 1914
The North African antelope cow
Cow antelope - a subfamily of the large antelopes that live in Africa. Of which there are several kinds, but particularly this kind virtually disappeared from the map of the Earth by the beginning of the XX century. Hunting for them was so active that the last few decades of its existence, the cow antelope found only in really remote places several African countries is not completely extinct by the middle of the last century.
Year of extinction: 1954
Even in the XIX century, the Javanese tiger met throughout the island of Java and regularly annoy its inhabitants. Maybe it was one of the reasons for the active hunt for him, and maybe something else, but the fact remains that in 1950 living on the island there are only 20-25 individuals. With half of these tigers lived in the territory of a specially created reserve. But even this was not enough to save the population, and by 1970 their number was reduced to seven individuals. The exact time of extinction of the Javan tiger remains unknown, but most likely, it happened in the mid-1970s.
From time to time there are reports that in Java again saw the Javanese tiger or even a mother with several cubs, but there is no documentary evidence that the Tigers really are preserved in nature, no.
Year of extinction: circa 1970
The destruction of Zanzibar leopard is both similar and not similar to the extermination of other species on our list. Leopard killed and killed deliberately and very active, announced on animals hunt, and walked them across the country. However, this was done not for the sake of its meat or hide, and not in order to save the village and the cattle from potential attacks of the animal. The fact that the population of Zanzibar archipelago was adamant that these leopards are associated with witches, the evil witch are specially bred and trained these animals his help, and then send leopards do for their nefarious deeds.
the extermination of animals campaign began in the second half of the 1960s, and after what some 30 years Zanzibar Leopard is almost gone in the wild. Scientists have begun to sound the alarm in the early 90-ies of the last century, but the program after several years of conservation of the species has been curtailed as a dead-end.
Year of extinction: the 1990s
