The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [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.
"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 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 .
The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found.. The study, titled the 2024 Living Planet Report, monitored ...
A shocking new report on global biodiversity is detailing what it calls "a catastrophic decline" in wildlife populations ahead of a ... dropped 88% since 1970. The Shasta Dam blocked off access to ...
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 .
When estimating the effect of climate change on species' extinction risk, the report concluded that global warming of 2 °C (3.6 °F) over the preindustrial levels would threaten an estimated 5% of the Earth's species with extinction even in the absence of any other factors like land use change. If the warming reached 4.3 °C (7.7 °F), they ...
“A lot of people don’t associate wildlife movement with climate change,” Kathy Rinaldi, the Idaho conservation coordinator for the Greater Yellowstone Coalition, said in a phone interview.
