Living Planet Index

The Living Planet Index (LPI) measures the overall health of the world’s wildlife populations by tracking the abundance of thousands of species over time. It provides an indicator of whether animal populations are increasing or decreasing globally, highlighting trends in biodiversity. A declining index signals that many species are facing threats such as habitat loss, climate change, and pollution, which can lead to reduced biodiversity and ecosystem stability. The LPI helps policymakers, scientists, and the public understand urgent conservation issues and the impact of human activities on the natural world.
