Living Planet Index - Biodiversity decline rings alarm bells
Since 1970, between 25% and 33% of the world’s wildlife has been wiped out.
The Living Planet Index, compiled by the society in conjunction with the World Wildlife Fund (WWF), tracks the fortunes of almost 1,500 species of fish, amphibians, reptiles, birds and mammals. The index shows that overall numbers have declined by a massive 27% in the 35 years between 1970 and 2005.
