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 ...
Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world. This type of biodiversity loss is known as one of the most critical threats to global biodiversity .

"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%)."
The Living Planet Report is the world's leading, science-based analysis, on the health of our planet and the impact of human activity. Humanity's demands exceed the Earth's capacity to sustain us. [1] The 2018 report found a "decline of 60% in population sizes" of vertebrate species overall from 1970 to 2014.
