Biodiversity

Biodiversity is the result of 3 billion 800 million years of evolution, and it is essential for the survival of mankind. In fact we depend on nature for many fundamental resources, among which food, building materials, heating, textile fibres and the active ingredients of medicinal products. Furthermore nature provides for other vital functions such as the pollination of plants, purification of the air, water and soil, etc. Today human activities are a severe threat for biodiversity, and they jeopardize the existence of numerous species. The destruction and fragmentation of the habitats, air, water and soil pollution, excessive fishing, the overexploitation of resources, forests and fields, the introduction of alien species and the emission of increasing amounts of gas with the greenhouse effect. that provoke climate changes, are only some of the causes of the loss of biodiversity.
