баланс кислорода

[juan_gandhi]

Не нашел нигде, как изменялся баланс кислорода на планете за последние, хм, 100 лет. На вики пишут, что его 21%.

Sure, but even with deforestation and phytoplankton decrease (and ballooning populations of oxygen- breathing humans and livestock) we are still not about to run out of oxygen.

Most of the oxygen is lost to carbon oxidation, so its depletion is roughly equal to increases in carbon dioxide (roughly because some of the CO2 is absorbed and released by oceans/bogs etc.). Therefore oxygen depletion for the last century should be at most about 0.01% - we are not about to run out.
