Biodiversity can be defined as the number of species living in a defined area and represents the most important resource of the ecosystems of our Planet. The destruction of the forests and habitats causes the extinction of thousands of species every year; because of this, the loss
of biodiversity is one of the greater environmental emergencies of our times. Unsustainable production and consumption models, lacking of education and consciousness at every level caused a loss of biodiversity to which other environmental emergencies like global warming and limited availability of resources are strictly related; in the next decades the solution of these problems will decide the destiny of the human community. Recognizing these priorities, United Nations declared 2010 to be the “International Year of Biodiversity”.
