In a new video, the University of Minnesota Institute on the Environment asks a critical question: “Have we pushed Earth past the tipping point?” Humanity developed civilization within a small zone of environmental conditions, but in the last century we have begun reshaping our planet, accelerating the process in recent years:

We’ve cleared, consumed and polluted our way across the globe. The planet is shrinking. Have we pushed Earth past the tipping point?

Watch the video:

Last September, a team of 28 scientists identified “10 separate biophysical systems crucial to humanity’s flourishing” and then determined “safe operating boundaries” for those systems within which humanity must remain if we wish to maintain the conditions in which it developed civilization. Unfortunately, anthropogenic interference with the climate system, the nitrogen cycle, and biodiversity is already past safe thresholds, with ocean acidification, ozone depletion, and other resource consumption at the door.
