What are the extinct animal species?
Animal disappeared when no specimens were left alive, although the walking skills may have ceased. Because many animals have a large natural habitat, it is often difficult to determine accurate extinction data. Historically, the extinction of animals was caused by many factors, including climate change, massive events of the planet, such as the impact of the meteor, predominant genetic problems and destruction predators. Most often in modern times, extinct animal species were largely killed by human influence, while some experts suggest that human interventions will cause half of all forms of life to disappear in the next century. In the animal world, the reality of modern animals is already understood.
One of the most famous of the extinct animal species was discovered only several decades before its disappearance. In 1741, German natural scientist Georg Stellar discovered a huge cousin Manatee living in the North Pacific Ocean. Stellar's sea cow, as called a fine creature, reached a length of up to 25.9 ft (7.9 m) and mThe announcement of up to £ 6,000 (£ 2,721) has carefully studied the animal and provided us with all the information that exists today. Due to hunting, the largest of the sirenian was extinct within 30 years.
One of the main causes of extinct animal species in Australia is the human import of non -native species of predators such as foxes and domestic cats. Small mammals, especially marsupials and birds, are not used by these aggressive predators and have little or no defense abilities against them. Since the 18th century, almost 30 Australian Marsupial and rodents have disappeared, including Bandicoot, Lesser Bilby, Eastern Hare-Wallaby and Velký Ears. Imported species are considered to be the primary cause of most of these extinction.
Modern extinction is often caused by the loss of habitat due to agricultural, industrial or urban growth. The subspecies of the Tiger Bali and Javan had a relatively small population that started, vzLooking for a limited range of their island houses. As the human population in Indonesia increased during the 20th century, the area of the habitat of both tigers was heavily exhausted. In 1937, Bali Tiger was declared extinct. Some attempts to preserve Javan Tiger were made, but the last known survivor of the species died in the 80s.
Pollution caused by man is also considered the main cause of extinct animal species. In 2006, the Chinese dolphin, called Baiji, was also called Baiji, after an exhaustive survey of Chinese biologists. It is assumed that Baiji, a freshwater dolphin, which lived exclusively in the Yangtze River, was unable to adapt to the commercial use of the river and the growing level of pollution.
in North America, recent estimates show 37 extinct animal species on the whole continent, all of them over the last 500 years. It is assumed that the eastern population of the North American bomb was hunted to extinction at the beginning of the 20th century. Several types of GophEru, including Goff's pocket gopher and Tacom Pocket Gopher, are listed as defunct animal species for the nature of nature (IUCN). On the east coast and the northern Atlantic Ocean Sea and Fox Falkland, they were hunted to extract for their backrests in the 19th century.
The list of extinct animal species assembled IUCN is added to each year and is maintained by the organization together with lists of critically endangered or endangered species. If you want to help protection, there are many organizations devoted to research and maintaining endangered animal populations. The use of biodegradable and environmentally friendly products can also help support the responsible use of resources by reducing the level of pollution and supporting sustainable procedures around the world.
