More than 16,000 animals and plants are at risk in the world… Over 500 species have entered the list, from the polar bear to the hippopotamus. Sharks and freshwater fishes are in difficulty. 16,119 animal and plant species out of 40,177 are considered endangered: 500 more than in 2004, when they were 15,589. 784 species are considered officially extinct, while 65 of them survive only in captivity. It is revealed by the new Red List of endangered species published today in Geneva by the IUCN (World Conservation Union), thanks to the work of over 1,000 scientists worldwide. One third of amphibians are at risk, one out of four mammal species and one bird out of eight, mainly because of climate change and habitat destruction because of the man.
"The question we must make is: Should we be happy to imagine that our grandchildren will not ever see any elephant, if not in a picture or in a movie?" David Attenborough
The rhino horn has been widely used in the past, but also in the present days: for example in Asia during the epidemic SARS flu, because - according to some traditional baseless medicines- it should have the property to lower fever.

In recent decades, not only population growth, but also growth of living standards have caused a huge push to build, which was carried almost exclusively at the expense of agricultural land. Between 1980 and 2008 1m² of land per second has disappeared under concrete or asphalt! (Schweiz Biozid- Report).
Disappearance of natural and semi-natural habitat: 1.Wetlands, floodplains and groundwater 2. Woods 3. Arid biotopes 4. Orchards 5. Hedges and groves 6. Pioneers environments
