Mar 1, 2021 · One billion years from now, Earth’s atmosphere will contain very little oxygen, making it uninhabitable for complex aerobic life. Today, oxygen makes up around 21 per cent of Earth’s...
Oxygen makes up one-fifth of the air we breathe, but it’s the most vital component – and it does seem to be declining. The main cause is the burning of fossil fuels, which consumes free oxygen. Fortunately, the atmosphere contains so much oxygen that we’re in no danger of running out soon.
Jul 19, 2024 · 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. It's getting harder to breathe down there.
Apr 6, 2022 · Global warming and greenhouse gas emissions aren’t the only factors driving ocean deoxygenation. Fertilizer runoff and sewage pollution deposit enormous amounts of nitrogen and other nutrients into coastal waters, which create watery feasts for fast-growing algae.
Oct 2, 2019 · At about 8 kilometers (5 miles) altitude, there’s insufficient oxygen in the air to sustain human life. At around 19 kilometers (12 miles) altitude, your blood boils unless you’re in a pressurized environment.

Stage 1 (3.85–2.45 Ga): Practically no O 2 in the atmosphere. The oceans were also largely anoxic – with the possible exception of O 2 in the shallow oceans. Stage 2 (2.45–1.85 Ga): O 2 produced, rising to values of 0.02 and 0.04 atm, but absorbed in oceans and seabed rock.
