WWF Campaign - If You See An Animal, You're Missing Something

Publications
WWF publishes the Living Planet Index in collaboration with the Zoological Society of London. Along with their ecological footprint calculations the index is used to produce a two yearly Living Planet Report to give an overview of the impact of human activity on the world.
The organization also regularly publishes reports, fact sheets and other documents on issues related to its work, in order to raise awareness and provide information to policy and decision makers.
