For the first time in the modern scientific record, humanity has pushed seven of nine planetary boundaries—the thresholds that define the conditions under which life as we know it can persist—to their worst-ever levels of violation. From the stability of the climate to the integrity of freshwater systems, from the web of biodiversity to the accumulation of chemical pollutants, the Earth's life-support architecture is under simultaneous and compounding strain. Scientists are not describing a future danger but a present condition: the planet's systems are being asked to bear more than they were
Scientists warn 7 of 9 planetary boundaries breached, risking irreversible Earth changes
Breached planetary boundaries threaten global food security, water availability, and habitability for billions of people.
