Species on the Earth are under increasing human pressure, according to some authors, the current rate of extinction occurred only a few times in the past, for the last time in the Cretaceous Period in the Mesozoic Era. The main goal of current nature conservation is to maintain the highest native biological diversity and to preserve and enhance life-supporting ecosystem processes, functions and services with the best possible use of financial resources. The areas where can be found the highest concentrations of endemic species and that also face the highest loss of natural habitats are called biodiversity hotspots. Globally, now there are 36 hotspots, covering 2.4 % of the Earth’s land area and harbouring about 50 % of endemic plant species and 42 % of endemic terrestrial vertebrate species in the world. The areas can be compared in terms of species richness, endemism, natural habitat loss or territorial protection and nature conservation can be carried out in the most efficient way. The most important hotspots are Madagascar and the Indian Ocean Islands and Sundaland.
