O2 & CO2 Availabilty?

Hello all,
Greetings!

Just trying to change the mood. Normal O2(Oxygen) and CO2(Carbon Dioxide) availably to us is very important for us and for all beings. There can be many factors which can affect it Eg, altitude, fuel burnings,pollution etc. However, I am just checking following factors in this topic:

1. Over or under greenery in surroundings(in view of O2 & Co2 release and intake by them(by photosynthesis and respiration).

2. Sea and other big water body nearby. Due to photosynthesis and dissolution of O2 & CO2.

3. High humidity: Due to dissolution of O2 & CO2 in water.

4. Temperature: due to its impact on dissolution rate of O2 & CO2.

5. High and concentrated inhabitants of beings: Due to over consumption of O2 & CO2.

I am not talking about overall earth's environment levels but talking about local levels.

Just look at it:
Quote:

Table 2: Annual gain and loss of atmospheric oxygen (Units of 1010 kg O2 per year)

Photosynthesis (land)16,500
Photosynthesis (ocean)13,500


Photolysis of N2O 1.3
Photolysis of H2O 0.03

Total gains ~ 30,000

Losses - respiration and decay

Aerobic respiration 23,000

Microbial oxidation 5100

Combustion of fossil fuel (anthropogenic)600
Photochemical oxidation12 10
Fixation of N2 by lightning
5
Fixation of N2 by industry (anthropogenic)
Oxidation of volcanic gases





Losses - weathering
Chemical weathering
Surface reaction of O3 50
12
Total losses ~ 30,000

Talk more on above bold figures.

For better picture look at following link:

Whether we compromise gases by change in respiration rate or air volume abnormally, should not be made a base for normal physiology. Any abnormality should matter.

Thanks and best wishes.
