WorldWildlife Fund Living Planet Report 2012

A sobering survey of the threat humans are posing to thousands of species of animals around the world, and to our own future. The report, which measures the health of 9,014 populations of more than 2,600 species, reveals a 30% decline in the health of species since 1970, and shows that we’re consuming 50% more natural resources globally than our planet can sustainably produce. The report is published every two years in collaboration with the Zoological Society of London and the Global Footprint Network.
