The planetary boundaries framework highlights the rising risks from human pressure on nine critical global processes that regulate the stability and resilience of the Earth, which includes “biosphere integrity”. Planetary boundaries are quantitative assessments of the safe limits for human pressure on these nine critical processes.
The seven breached planetary boundaries are: Climate Change, Biosphere Integrity, Land System Change, Freshwater Use, Biogeochemical Flows, Novel Entities, and Ocean Acidification (new in 2025). All of these seven boundaries show worsening trends. Only Ozone Depletion and Aerosol Loading remain in the safe zone. (Planetary Health Check, 2025)
