The World Wildlife Fund published its 2026 Living Planet Report in October, finding that the average population size of wild species has fallen by over 70% over the past 50 years. The report uses the Living Planet Index to track the world's biological diversity.
Why it matters
The findings quantify a long-term decline in global biodiversity over half a century, providing a measure of how wildlife populations have changed worldwide. The report also highlights that targeted conservation efforts have allowed some species populations to recover.
The figure is drawn from the Living Planet Index, which tracks population sizes across wild species over 50 years. The source does not detail the breakdown of species or regions contributing to the decline.
The players
World Wildlife Fund
The World Wildlife Fund is an international conservation organization that publishes the Living Planet Report, which tracks global biodiversity trends.
The details
Tigers, bluefin tuna, and green turtles have seen population increases through conservation efforts, according to the report. The decline measurement covers the average across wild species tracked by the index.
Timeline
Over the past 50 years: average wild species population fell more than 70%.
October 2026: World Wildlife Fund released the 2026 Living Planet Report.
Big Picture
The 2026 Living Planet Report extends the Living Planet Index as the primary measure of global wildlife population change over five decades. Its finding of a more than 70% average decline is the figure the index is designed to produce.
Readers concerned about wildlife can look at conservation efforts like those that helped tigers, bluefin tuna, and green turtles recover. The decline figure applies to wild species generally, so individual regional experience may vary.
The takeaway
Conservation efforts have measurably helped some species recover even as average wild populations have declined sharply. Tracking long-term population data like the Living Planet Index shows where protection is working.
