Inglise keele report: Animals in danger of extinction

Subject: Animals in danger of extinction Date: 20.04.11 The aim of this report is to make an overview of the status of wild animals in the world. The report is based on up-to-date statistics related to the topic. There are several disappointing facts and figures. a) Over the last couple of years the list of animals in danger of extinction has grown rapidly. The International Union for Conservation of Nature (IUCN) has calculated the percentage of endangered animals as 40 percent of all organisms. Recent research indicates that 70% of the world's most threatened mammal species are currently receiving little or no conservation attention.On 29 January 2010, the IUCN Red List of Threatened Species identified 842 extinct species and subspecies....

My mother tongue in 21th century

They also use slang too much. It's quite possible, that soon the Estonian language dies out and replaces with English. The second reason, why Estonian is in big danger, is because the little importance of the language. Almost everyone can speak at least one foreign language and nowadays the travelling possibilities are also very good. So if the Estonian language has no importance, it's possible, that if several nations will mix and there will be no Estonian anymore. Estonian language is nearing extinction in the 21th century. People should think more about the importance of the language and protect it from foreign influences....

Inglismaa

Some wetland areas have drained and are now covered by towns and farmland. Animal life An estimated 30,000 animal species live in Britain, although many of them are on the endangered list. Britain has many small mammals and the large ones tend to be gentle. The only surviving large mammals are red deer and roe deer. Semi wild ponies also inhabit the Shetland Islands. Once wild boars and wolves roamed Britain but they were hunted to extinction . Small mammals like badger, foxes, otters, red squirrels and wildcats inhabit Britain. Wildcats are found only in parts of Scotland. Britain has five species of frogs and toads and three species of snakes. There are no snakes in Northern Ireland. Bird watching is a popular national pastime. Britain is home to a large variety of birds. About 200 species are regularly seen. The most common ones are those which remain all...

Topic - Great Britain

Song birds in particular are becoming scarcer and habitat loss has affected larger mammalian species. Some species have however adapted to the urban environments, such as the Red Fox, which is the most successful urban mammal after the Brown Rat. Large mammals are not very numerous in GB. Many of the bigger species, such as the Grey Wolf and the Brown Bear were hunted to extinction many centuries ago. However, recently, many of these large mammals have been reintroduced to some areas of mainland Britain. The largest mammals that remain in Britain today are members of the Deer family (for example: the Red Deer) Plants ­ The mild climate, ample rain and long growing season support a great variety of plants, which grow exceptionally well. Sometimes plant growth is compared to the lush areas of the well-watered and mild coasts of the states of Washington and Oregon...

The importance of the rainforest

If nothing is done to curb this trend, the entire Amazon could well be gone within fifty years. Massive deforestation brings with it many ugly consequences-air and water pollution, soil erosion, malaria epidemics, the release of carbon dioxide into the atmosphere, the eviction and decimation of indigenous Indian tribes, and the loss of biodiversity through extinction of plants and animals. Fewer rainforests mean less rain, less oxygen for us to breathe, and an increased threat from global warming. But who is really to blame? Consider what we industrialized Americans have done to our own homeland. We converted 90 percent of North America's virgin forests into firewood, shingles, furniture, railroad ties, and paper. Other industrialized countries have done no better....

Ireland report

rabbits and the brown rat. About 400 species of birds have been recorded in Ireland. Many of these species are migratory. There are arctic birds, which come in the winter, and birds such as the swallow, which come from Africa in the summer to breed. Ireland has a very rich marine avifauna, with many large seabird colonies dotted around its coastline such as those on the Saltee Islands and Skellig Michael. Also of note are golden eagles, only recently reintroduced after decades of extinction . There are no snakes and only one reptile native to Ireland, the common lizard. There are three amphibians, the common frog, the smooth newt and the natterjack toad. Certain marine turtle species appear regularly off the south west coast but do not come ashore. Flags of Ireland The state flag applying to Northern Ireland is the Union Flag of the United Kingdom of Great Britain and Northern Ireland. The state flag of the Republic of Ireland is the Tricolour...

White Tiger

Many people see the tigers as beautiful animals, which are necessary for the protection of extinction . Tigers are being killed for many reasons. The population of White Tigers outside captivity is hard to estimate, since they are not seen very often in their natural habitat. The future of the Bengal Tiger and the White Bengal Tigers does not look very bright. Cubs Cubs from White Tigers are either white or yellow. The pregnancy lasts for only 15 weeks. The cubs are born blind, just like notmal cat kittens. The cubs stay with their mother for 23 years....

Animals we miss today

Causes: *The main cause of animal extinction , without doubt,is human demand, either for animal resources directly, or for the natural resources of the animals' habitats. *In addition to that, there are other indirect causes caused by human activities. *Habitat loss: Is considered to be the main cause for animal extinction. Humans are clearing our forests for wood and timber. The foodchain is disturbed and animals will die. *Wildlife trade: Poaching and wildlife trade are another common threat to animals. International wildlife trade has also been linked to drugs trade. The most common anilmal trade is pet trade, such as orangutangs. Animals are also killed for fur(tigers, leopards, cheetahs) *Climate change: It has been recently suggested that warmer global temperatures may be affecting animals...

Rare animals

One of the difficulties is the beetle's life cycle ­ the larvae of bombardiers prey on beetles in the Amara genus, but it is not known precisely which ones. "This is the last chance saloon for the beetle ­ if nothing is done, the species will be lost anyway," Roberts said. Only a handful of streaked bombardier beetles have been found and moved so far, and with time running out before the building work begins, extinction is imminent for a species that was only recently added to the UK's red list of endangered species. Can China's rare `bear' survive? Pandas are not a species at an `evolutionary dead end' as is sometimes claimed, according to new research that has been carried out by scientists at Cardiff University and in Sichuan in China. Previous findings have suggested that the serious decline in giant panda numbers in modern...

Australia topic

Emus are farmed for their meat, oil and leather. The Kangaroo is a common marsupial from the islands of Australia and New Guinea. There are 47 species of them. Kangaroos can hop up to 74 km per hour and go over 9 m in one hop. These shy animals live about 6 years in the wild and up to 20 in captivity. Most of them are active at night. Many kangaroos are in danger of extinction . Kangaroos eat grass, leaves, and roots. They swallow their food without chewing it and later regurgitate a cud and chew it. They need little water; they can go for months without drinking, and they dig their own water wells. The Dingo is Australia's wild dog. It is found in Australia, in all states but Tasmania. They are found throughout the mainland of Australia, close to a source of water...
