Millennium Ecosystem Assessment

In nature, everything is interrelated. Climate change, together with changes in the uses of the soil, is one of their main causes of biodiversity loss. At global level, the UN provides worrying data; three disappear each time i species each year are extinguished between 18,000 i 55,000 species. This will be one of them findings of the Millennium Ecosystem Assessment, an ambitious report presented by the UN. Then, the loss of biological diversity and the deterioration of natural habitats such as forests, mangroves or coral reefs contribute to global warming. According to a study of the Secretariat of the Convention on biological diversity, before this century ends, i species les ecosystems will have many difficulties to adapt to changes in temperatures and precipitation, which will accelerate the pace of extinctions.

Some very vulnerable species are the polar bear (do periods with the? ice knowing are increasingly more shorts), Atlantic right whale (climatic fluctuations reduce the) (plankton, a food), frogs (which depend on the availability of water to reproduce), Asian Tiger (which depends on mangroves, doomed to disappear if you increase the sea level), or African elephants (increasingly more pressured by lengthening periods of drought). The UN warns that the preservation and sustainable use of biological diversity are essential in any strategy of adaptation to the climate canbio. Thus for example. Mangroves and other coastal wetlands protect against extreme weather and the increase of the sea level. On the other hand, the diversity of herds and cereal crops allow farmers find alternatives to adapt to desertification and the progressive warming of agricultural land.
