Scientists sound caution on nitrogen pollution at INI conference June 01, 2021
Humanity’s failure to stop nitrogen pollution could limit the safe operating margin for many other issues facing our planet earth, said scientists. “Human activities have pushed climate change, biodiversity loss, shifts in nutrient cycles (nitrogen and phosphorus) and land use beyond the tolerance limits of planet earth. The difficulty is that they also limit the safe margin available for other environmental issues facing the earth, such as fresh water use, ocean acidification, land use and stratospheric ozone depletion,” said Johan Rockstrom, former director of the Stockholm resilience centre at the Stockholm University, Sweden.
