A major new scientific review, “Planetary Health Check 2025”, shows that seven of nine planetary boundaries have now been exceeded. For the first time, this also includes the boundary for ocean acidification. This means that several of Earth’s life-supporting systems risk crossing critical thresholds, with severe consequences for both ecosystems and societies.

The seven breached 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.

And these boundaries are not tipping points—it’s possible to recover from passing them—but they are thresholds signifying we’ve entered higher-risk territory.
