Currently the oxygen content in the atmosphere on world average is 20.9%. This is a pet inquiry of mine and a friend who is an environmental technician in the tropics. What we are finding out the oxygen levels are not being published. We will always see the CO2 content but never the oxygen content. Indications from ice boring and is depending on which research; the oxygen content either 100 years ago or 400 years ago was 38%. The percent level where animals begin to degrade is 13% and under 6% we can not live. Oxygen content for many regions vary between 12% to 18%. Certain cities the content levels can be dangerously low. From a very reliable resource two days ago stated, areas in Japan the oxygen level was 6%.

It's difficult to imagine but we're running out of air to breathe. The areas in the world where the oxygen contents are under 13% must be having a severe effect on peoples health and child development.

I believe the hazard guess is probably accurate. But the oceans are dying..... we are seeing more and more dead zones and fish dying off in schools, especially in the tropics.
