Humans are pushing Earth beyond safe levels of heat, pollution, and other conditions, threatening both our survival and that of millions of species. The Planetary Health Check from the Potsdam Institute for Climate Impact Research reveals that seven out of nine critical environmental boundaries are at their worst levels since they were first identified in 2009. These boundaries are essential for maintaining a habitable planet. The report highlights that human activities, such as burning fossil fuels and excessive fertilizer use, have already breached these limits, with ocean acidification being the latest. Surpassing these boundaries increases the risk of irreversible environmental changes. For instance, carbon dioxide levels have reached a record high of 426 parts per million, far exceeding the preindustrial level of 280 ppm and the “safe” limit of 350 ppm. This situation underscores the urgent need for action to prevent further environmental degradation.
QUESTION: How might the continued breach of these planetary boundaries impact your future and the world you live in?
9 ‘boundaries’ keep Earth livable. We’ve breached 7 of them
