Man and biodiversity

Due to the growth in the human population, in production and consumption, over the last two centuries the natural ecosystems of our planet have been subjected to an impressive depletion of their biodiversity, with an overall decrease, measured by the Living Planet Index, equal to 30% from 1970 to 2005. Human activities have increased the rate of natural extinction and it is estimated that the current climate change will worsen the situation further. Biodiversity is important as a value itself, also because it contributes to human wellbeing: the vegetable components and the fauna in the forests are an important source of food for many local populations, they are a source of active ingredients (25% of the drugs), they contribute to increasing the revenue and freedom of choice of the local populations, they are remarkably important in social relations and conservation of the cultural heritage.
