The WWF (World Wide Fund for Nature) Living Planet Report 2026 recorded an average 73% fall in monitored vertebrate population sizes between 1970 and 2022. Its Living Planet Index (LPI), compiled by the Zoological Society of London (ZSL), follows 35,803 population trends covering 5,790 vertebrate species. Freshwater ecosystems saw the steepest drop (85%), followed by terrestrial (69%) and marine (59%) ones. Key drivers are habitat loss, overexploitation, climate change, invasive species, pollution and disease. On a positive note, global wild tiger numbers rose from about 3,200 in 2010 to 5,700 in 2025.
