Oxygen, after all, is the most acutely limiting resource for human survival.

In other words, the pure oxygen a quarterback might huff between plays, or that a jet-lagged traveler might shell out 50 dollars for at an airport “oxygen bar,” are of no benefit.14 Inhaling the gas might increase blood oxygen levels one or two percent, but that oxygen will never make it into our hungry cells. We’ll simply breathe it back out.fn1 T

The oxygen needed for nucleotides would come from water.

three existential necessities: oxygen, water, and food.

The beginnings of the oxygenated atmosphere go back to what has become known as the Great Oxidation Event, which began about 2.5 billion years ago.[7] During that period, oxygen released by oceanic cyanobacteria began to accumulate in the atmosphere, but it took a long time before the gases reached their modern concentrations.

The crucial point to remember is that haemoglobin releases oxygen when in the presence of carbon dioxide.

Cloud proposed that, incredibly, in the ocean, huge green mats of these tiny photosynthesizers, which we know as cyanobacteria, pumped so much oxygen into the atmosphere that they rusted the Earth’s surface. First, oxygen rusted the iron in exposed rocks on the continents, which weathering, rain, and rivers swept into the ocean. Then, as the cyanob

The End of All Disease Current carbon dioxide levels in sea level air are currently only 0.04% and oxygen levels are 21%963 - an environment that Dr. Buteyko once called ‘poisonous in its composition;’ containing 10-times more oxygen and 250-times less carbon dioxide than what our bodies need. “…the cells of animals and humans need about 7% CO2 and
