Deforestation to create plantations is considered to be one of the threats for the animals.
As people expand the use of the land for the life the animals have less territory. There is a risk that by 2070 through human activity 1700 species of amphibians, birds and mammals is on the brink of extinction, informs Rus.Media.
To such conclusion ecologists from the University of Wales. In the work, the scientists combined information about the current geographical distribution of about 19 400 species worldwide changes of Land associated with human activity, and designed different development. These potentials represent expectations about future events in a global society, demography and economy.
“The results of our studies link these likely options for the future with their consequences for species diversity. Our analysis allows to trace how political and economic decisions through related changes in global land cover will reduce habitat of species in the world,” says fellow Welsh University and one of the authors Walter Dietz (Walter Jetz).
The study shows that the preservation of trends in land use by man, the extinction risk of about 1700 species in the next 50 years is likely to increase: the animals will lose about 30-50 percent of the usual habitat by 2070. List of species of concern, includes 886 amphibians, 436 376 birds and mammals.
Special concern species of frog Oreophryne monticola in Indonesia, Sudanese goat (also known as Nile lychee) and two birds of the family ponikva: Cichlocolaptes leucophrus in Brazil and Limnornis curvirostris in Argentina, Brazil and Uruguay. These species, according to environmentalists, will lose about half of modern geographical range in 50 years.
The species inhabiting Central and East Africa, Mesoamerica, South America and South-East Asia experiencing the greatest loss of habitat and increased risk of extinction. However, experts warned against the erroneous assumption that this is a problem solely of those countries on whose territory there are such processes.
“Losses in the populations of species can irreversibly hamper the functioning of ecosystems and quality of human life. Although the decline of biodiversity in remote parts of the planet may not have a direct impact on us, its consequences for human life can be reflected at the global level. These losses are often the result of certain human needs, such as tropical hardwoods, palm oil or soy beans, which makes us responsible,” says Dietz.
So, deforestation to create plantations is considered to be one of the threats for the animals. For example, high demand for Durani in China caused a new wave of deforestation of the Malaysian forests, and for the production of cheap palm oil, an increasing number of palm plantations.
