In order to make fire, one needs three things. A heat source, fuel, and oxygen. The by product of fire is often carbon monoxide. So every jet, car, bus, truck, home gas furnace, missile, bomb, forest fire, gas water heater, coal power plant all burning oxygen. Then you add all oxygen breathing organisms on the planet to the list. Now take that number and put it against the ever dwindling plant life that is responsible for the creation of oxygen.
A human breathes about 9.5 tonnes of air in a year, but oxygen only makes up about 23 percent of that air, by mass, and we only extract a little over a third of the oxygen from each breath. That works out to a total of about 740kg of oxygen per year. Which is, very roughly, seven or eight trees’ worth.
The world population was estimated to have reached 7.5 billion in April, 2017. The United Nations estimates it will further increase to 11.2 billion in the year 2100. That is just humans. Not animals, not fire causing devices. Not wild fires.
When oxygen levels are at... ...a person experiences:
21. percent -Normal outside air
17. percent -Impaired judgment and coordination (just from a 04 drop)
12. percent -Headache, dizziness, nausea, fatigue
9. percent -Unconsciousness
6. percent -Respiratory arrest, cardiac arrest, death
So fire consumes oxygen... So when does the consumption of oxygen out compete the rate of its creation? Interesting to note that only air breathing whales wash ashore alone with no obvious signs of death. Not fish.... Imagine if the death of dinosaurs was due to a loss of oxygen, just enough to affect the larger animals who might require a higher oxygen atmosphere but not the smaller ones..... Why are humans able to breath with so little oxygen present? What would happen to a human grown in a pure oxygen environment free of pollutants?
