[1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.

The 2018 report found a "decline of 60% in population sizes" of vertebrate species overall from 1970 to 2014. The tropics of South and Central America had an 89% loss compared to 1970. [ 2 ] These claims have been criticized by some studies such as the research group led by Brian Leung and including Maria Dornelas .
There is some debate over the severity of declining trends in the global mammal and the broader vertebrate population: while the Living Planet Report of the World Wide Fund for Nature reported a 68% decline in the aggregate wild vertebrate populations since 1970, [39] [40] [4] a scientific reanalysis of its data in Nature found that 98.6% of ...
"Data source: World Wildlife Fund (WWF) and Zoological Society of London" Source for Version 1 states: "The Living Planet Index (LPI) measures the average decline in monitored wildlife populations. The index value measures the change in abundance in 31,821 populations across 5,230 species relative to the year 1970 (i.e. 1970 = 100%)."

Red list categories of the IUCN Demonstrator against biodiversity loss, at Extinction Rebellion (2018).. The current rate of global biodiversity loss is estimated to be 100 to 1000 times higher than the (naturally occurring) background extinction rate, faster than at any other time in human history, [25] [26] and is expected to grow in the upcoming years.
