The Living Planet Report is a periodic update on the state of the world's ecosystems produced by the Worldwide Fund for Nature (WWF).

WWF have developed what they call the Living Planet Index. The index is based on trends over the past 30 years in populations of hundreds of species of birds, mammals, reptiles, amphibians and fish.

Between 1970 and 2000, the forest species population index declined by about 15 per cent, the marine index fell by about 35 per cent, while the freshwater index dropped 55 per cent over the 30-year period.
