Oxygen is a fundamental requirement of life, and the loss of oxygen in water, also referred to as aquatic deoxygenation, is a threat to life at all levels. In fact, in research recently published in Nature Ecology and Evolution, Rensselaer Polytechnic Institute’s Associate Professor Kevin Rose, Ph.D. and his collaborators describe how ongoing deoxygenation presents a major threat to the stability of the planet as a whole.
Previous research has identified a suite of global scale processes, referred to as Planetary Boundaries, that regulate the overall habitability and stability of the planet. These processes include things such as climate change, land use change, and biodiversity loss. It has been argued that if critical thresholds in these processes are passed, then major ecological, economic, and social challenges are likely to result. Importantly, Rose and collaborators argue that aquatic deoxygenation both responds to, and regulates, other Planetary Boundary processes.
“It’s important that aquatic deoxygenation be added to the list of Planetary Boundaries,” said Rose. “This will help support and focus global monitoring, research, and policy efforts to help our aquatic ecosystems and, in turn, society at large.”
