The Global Living Planet Index. The index shows a decline of 28% from 1970 to 2008, based on 9,014 populations
of 2,688 species of birds, mammals, amphibians, reptiles and fish. Shading on this, and all Living Planet Index figures represents the 95% confidence limits surrounding the trend; the wider the shading, the more variable the underlying trend (WWF/ZSL, 2012).
