Loss of oxygen in bodies of water identified as new tipping point

15.07.2023/Kiel/New York. Oxygen concentrations in our planet's waters is decreasing rapidly and dramatically – from ponds to the ocean. The progressive loss of oxygen threatens not only ecosystems, but also the livelihoods of large sectors of society and the entire planet, according to the authors of an international study involving GEOMAR published today in the scientific journal Nature Ecology and Evolution. They call for the loss of oxygen in water bodies to be recognised as another Planetary Boundary in order to focus global monitoring, research and political measures.
