"That means in just my lifetime, 50 years, we've seen a decline of 73% in the average size of these wildlife populations," noted Dr. Robin Freeman, global biodiversity expert with the Zoological ...
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.
The 2022 report found that vertebrate wildlife populations have declined by an average of almost 70% since 1970, and attributes the loss primarily to agriculture and fishing. The estimate was based on an analysis of 32,000 populations of 5,230 animal species.
The decline of wild mammal populations globally has been an occurrence spanning over the past 50,000 years, at the same time as the populations of humans and livestock have increased. Nowadays, the total biomass of wild mammals on land is believed to be seven times lower than its prehistoric values, while the biomass of marine mammals had ...

The World Wildlife Fund's Living Planet Report 2024 found that wildlife populations declined by an average 73% since 1970. [32] [33] [34] During the last century, decreases in biodiversity have been increasingly observed. It was estimated in 2007 that up to 30% of all species will be extinct by 2050. [4]
