This phrase seems to work better: "Utube, HISTORY FOR SLEEP, What 35% Oxygen Did to Life on Earth"
There seem to be similar videos, I cannot fetch the one I am listening to.
But in the video, a brief comment pushed me, it seemed to say that during the "Carboniferous" high Oxygen enhanced photosynthesis.
When I tried to confirm this my AI guide strongly disagreed. It said for higher, plants lower Oxygen levels enhance photosynthesis.
I may have misunderstood, or perhaps multiple types of photosynthesis react differently to Oxygen level.
So, this may suggest that in making places to grow plants under light either, from the sun or artificial, a lower Oxygen level may be of a benefit.
Forgive me please if I am mistaken. In C3 photosynthesis I read that Oxygen is a problem where it damages the process of Photosynthesis. The plants can only partially counteract its interference with productive photosynthesis. So, if may be that lower Oxygen levels make it easier for the plants.
The Oxygen levels of Earth are going down a tiny level due to burning The Earth is greening, but that is most likely due to elevated CO2 levels.
But if we build habitats in space where we expect to grow green plants, we may not want the equivalent Oxygen level of our 21% atmosphere on Earth. Lower Oxygen levels may promote plant productivity, it seems.
Lower Oxygen levels may also reduce fire risk.
But lower Oxygen levels may be problems for things like pollinating insects. But lower gravity may reduce the energy they have to expend to fly. I guess hummingbirds might be a substitute for insect pollinators. Probably insects from Alpine flowery places would be a good place to look for suitable pollinators.
It would be nice to also satisfy human needs however: https://www.sciencing.com/minimum-oxyge … ing-15546/ Quote:
Minimum Oxygen Concentration For Human Breathing
By Mallory Malesky Updated Mar 24, 2022Read More: https://www.sciencing.com/minimum-oxyge … ing-15546/
My current notion is that humans may have Oxygen masks of some kind, perhaps that can enhance Oxygen levels in a low Oxygen mix. Quote:
Humans need oxygen to live, but not as much as you might think. The minimum oxygen concentration in the air required for human breathing is 19.5 percent. The human body takes the oxygen breathed in from the lungs and transports it to the other parts of the body via the body's red blood cells. Each cell uses and requires oxygen to thrive. Most of the time, the air in the atmosphere contains the proper amount of oxygen for safe breathing. But at times, the level of oxygen can drop due to other toxic gases reacting with it.

Oxygen Concentrator, (Removes Nitrogen to make a higher Oxygen level).

Oxygen concentrator
From Wikipedia, the free encyclopedia
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are used industrially, to provide supplemental oxygen at high altitudes, and as medical devices for oxygen therapy.[1]
Not all greenhouses would have to have low Oxygen levels, but perhaps to enhance productivity and avoid fires, low Oxygen levels might be used. Perhaps just a bit lower.
This may suggest the levels tolerable without a Oxygen Mask: Quote:
Not Enough Oxygen: Side Effects
Not Enough Oxygen: Side Effects
Serious side effects can occur if the oxygen levels drop outside the safe zone. When oxygen concentrations drop from 19.5 to 16 percent, and you engage in physical activity, your cells fail to receive the oxygen needed to function correctly. Mental functions become impaired and respiration intermittent at oxygen concentrations that drop from 10 to 14 percent; at these levels with any amount of physical activity, the body becomes exhausted. Humans won't survive with levels at 6 percent or lower.Read More: https://www.sciencing.com/minimum-oxyge … ing-15546/
I think this may open interesting methods to increase productivity while keeping risk to humans relatively low.

Is it possible that the root of political science claims is to produce white collar jobs for people who paid for an education and do not want a real job?

Biosphere 2 may be suitable for a study. Perhaps it already has some data.

Does not sound too encouraging, but maybe there is data to help confirm or refute what I said in post #1.
