Two-thirds of the Earth’s ecosystems are in a critical condition – Scientists – Your city Pskov

The researchers report that the world will soon face mass extinction and a sharp reduction in the number of animals. This say scientists in a paper published in the journal Science. Most of these effects will only know about yourself in the future, so long as the world population can not understand all scale disaster, the scientists explain. Biologists and ecologists are not sure how many changes will be able in the modern world to survive one or another ecosystem, until the time until it is threatened with extinction.

Scientists from University College London have made an extensive database of species on Earth , which included 40 thousand. various forms of life and 2 million evaluations of their species diversity. The acquired data the researchers used to assess the biomes -. The components of the Earth’s biosphere, which include hundreds of connected with each other biosystems and ecological communities, located in the same climatic zone

The biosphere of the Earth is divided into 14 major biomes, in other words, global . ecosystem associations

Analysis of Newbold and his colleagues led to the disappointing conclusion – 58% of these biomes is now in critical condition

The collapse of ecosystems is most noticeable in the central regions of the United States and Canada, and Australia. , the southern regions of Russia and Europe, in Central Africa and southern South America.

in the world only tundra, taiga and subtropical broadleaf forests are relatively safe. All other types of biomes are the mark of 20% of extinct species, and they are now in danger of a sharp reduction in species diversity.

How can this fight? Economic losses from this may initially be high, but the subsequent degradation of ecosystems will lead to more not less “expensive” consequences, the scientists conclude.
