do we get most of our oxygen from the ocean?
How does that happen?

The majority of the Earth's Oxygen is produced by Photosynthetic single celled organisms in the upper layers of the ocean (down to 100 ft.). Most of these organisms are bacteria.
Oxygen in the earth's atmosphere is in an equilibrium state because of the myriad of life processes.

No, we get our oxygen from the atmosphere.
A couple of billion of years ago, the atmosphere was mainly CO2, plants turned than into free oxygen over time.
The oxygen in water is bound with hydrogen, the only natural process that casually release oxygen from water is, again plants (CO2 + H2O + light energy = sugar + free oxygen O2).
The amount of water thus "degraded" is minimal and negligible, and is actually returned to water when the plants are consumed, burned or decayed.

no. not at all. We get most of our oxygen from plantlife. One of the reasons for the lower o2 levels is that we are burning so much of the rainforest to raise livestock, that it has cut back on o2 production for the entire planet.
Plant more trees!!!

Like everything else, it probably comes from China.
I've heard a lot of it comes from the rain forests.
