The Spanish Mediterranean will lose a quarter of its plants in

The planet Earth is not only suffer the effects of climate change by increasing temperatures.
There are also other factors that affect global biodiversity, such as changes in land use, the
concentration of carbon dioxide, acid rain or the invasion of alien species that transform native
habitats. With these elements in hand, scientists have developed a UN report which presuppose the
evolution of terrestrial ecosystems in this century. In it, the most serious threats are borne on
the Spanish Mediterranean, which could lose up of its plants in .The change scenario that scientists predict located in red places on Earth where the
transformations of biodiversity are deeper. Thus, next to the Iberian peninsula appears whole
Mediterranean area, California, Chile's border with Bolivia, the region of Kurdistan and some
points of South Africa and Australia. Behind them, the Russian steppe, the center of North
America and a small portion between Argentina, Uruguay and Brazil. In all these places,
scientists predict serious threats to ecosystems by "massive extinctions" of fauna and flora. The
most favorable scenarios speak of a loss of bef the species, although the Spanish Mediterranean they could reach betwe, according to the report Ecosystem
Assessment Millennium, prepared by experts countries.
The change in land use is the most serious of which affect global biodiversity. For example, the
conversion of farmland pasture or tropical forests, land rustic newly urbanized or deforestation
has resulted in local extinctions of plants and animals, whose habitat is largely determined by
the composition of plant species. The bodies underground also severely affected by the overuse of freshwater resources.
This scenario, coupled with the invasion of alien species, threatening the biodiversity of the
Mediterranean in general and English in particular basin. In the case of Spain, lead author of
the report, Professor of Biology Osvaldo Sala, presented yesterday at the BBVA Foundation.
