According to the data Keeling has meticulously collected since 1989 the world is running out of breathable air—and the rate that it’s losing oxygen is now on the verge of accelerating.
Warning signs mounting
Warning sign one: oceanic dead zones
The first sign of oxygen depletion occurs in the oceans. Dead zones—regions where oxygen has been depleted and life can no longer exist—were first documented in the late 1970s. As time progressed, researchers discovered the dead zones were growing in size and number. New dead zones were discovered and life in those areas either moved or died.
According to Carl Zimmer the New York Times science reporter, “the area of the global ocean without enough oxygen for animals to survive (less than 70 micromoles per kilogram to be exact) expanded by 4.5 million square kilometers (1.7 million square miles). That’s an area about half the size of the United States.”
At the Danish Center for Earth System Science Gary Shaffer’s worst case scenario predicts that the oxygen levels in the oceans may drop by more than 20 per cent in the years ahead.
Warning sign two: forest charcoal
Forest fires provide a measurement of the ongoing depletion of Earth’s oxygen. Fires in an oxygen rich environment leave little or no carbon residue. The less oxygen available for combustion, the more charcoal remains as fire is unable to consume all the combustible material……..
