For a quarter century, mankind has destroyed every tenth wilderness


If people continue their “offensive” in the wild, by the year 2100 on any continent it will remain as such. With such a forecast made by Australian scientists from the University of Queensland. Experts also noted that humanity has already achieved considerable success” on this rather dubious field — for 25 years the Earth has lost about 10 percent of once pristine wilderness areas.

As the researchers report, for two and a half decades, the people intervened in the lives of countless ecosystems. The purpose may be, for example, search oil, gas and mining of other minerals, illegal cutting of trees or deliberate arson of forests in order to clear space for-use in agriculture. All this, according to the scientists, destroy the natural habitats of many animals, including those threatened with extinction.

To the conclusion that the tenth part of “untouched” land fell victim to human progress, the researchers came, comparing compiled in different years, special cards, which “wilderness” was noted. The comparison showed that in the early 90-ies of the last century about a third — 33 percent — of the total land area could be considered as a whole is not exposed to the modern man. However, since about 3 million square kilometres of these territories were “occupied” civilisation. It mostly felt the Amazonian lowlands in South America where the total area of wilderness areas has decreased by almost a third, and Central Africa, where it decreased by 14 percent. In this wild life of Australia, according to scientists, a quarter of a century in comparison with other continents suffered slightly. Relatively intact are North America and Northern Asia.

Experts believe that their findings indicate the need for additional measures for the protection of wildlife. A new study published in the journal Current Biology.
