WWF's Living Planet Report 2014 is a scientific study analyzing the health of the planet and the impact of human activities. The report, launched globally on September 30, 2014 in Geneva-Switzerland, records more than 10,000 vertebrate species populations from 1970 to 2010, through the Living Planet Index, a database maintained by the Zoological Society of London (ZSL). Measurements for the human Ecological Footprint are made by the Global Footprint Network (GFN).
