Supplies of dissolved oxygen in bodies of water across the globe are dwindling rapidly, and scientists say it's one of the greatest risks to Earth's life support system.

Just as atmospheric oxygen is vital for animals like ourselves, dissolved oxygen (DO) in water is essential for healthy aquatic ecosystems, whether freshwater or marine. With billions of people relying on marine and freshwater habitats for food and income, it's concerning these ecosystems' oxygen has been substantially and rapidly declining.

A team of scientists is proposing that aquatic deoxygenation be added to the list of 'planetary boundaries', which in its latest form describes nine domains that impose thresholds "within which humanity can continue to develop and thrive for generations to come."

So far, the planetary boundaries are climate change, ocean acidification, stratospheric ozone depletion, interference with the global phosphorus and nitrogen cycles, rate of biodiversity loss, global freshwater use, land-system change, aerosol loading, and chemical pollution.

Comment: What's particularly notable is that Earth's history shows that deoxygenation events, also known as anoxia, have occurred numerous times in the past, and it often seems to coincide with a variety of other phenomena, including climate change - more specifically global cooling - and mass extinction events (none of which occurred as the result of CO2): See also: Volcanoes, Earthquakes And The 3,600 Year Comet Cycle
