We consume Oxygen directly by breathing, and causing or allowing it to react in obvious dramatic activities like starting a fire or simply leaving an cut apple to turn brown as is slowly oxidies. We also cause oxygen to be consumed/used by, say turning on a light by burning gas or coal at a power station.
I have no idea of how to calculate the second part of that list but a first approximation of the first part, human respiration, should simply be the product of an estimate of the amount of oxygen used (not simply breathed) per unit time and the population in question.
I have read several sources and it appears that throuhg day/night, winter/summer etc. we use about 10 cubic feet of Oxygen a day.
The population of the Earth is not static but let's take it to be 7.1 billion.
So, in an average year 10 ft3 x 365 x 7,100,000,000 = 7.36*1013 ft3 Oxygen will be consumed by the people of the Earth.
HOWEVER that's not a really useful answer as it's not included the other uses or consumption of Oxygen mentioned at the start. It does not give a context for the vast number we just produced (are we teetering on the edge of our requirements? will the next million trees felled take us into Oxygen decline?)
ADDITIONALLY once you have breathed in Oxygen and used the energy and reactivity in staying alive we eventually (minutes/hours) return it to the atmosphere in several forms including the C2O we breathe out which will, in all likelihood be taken up by vegetative respiration and, in the great roundabout of life, release Oxygen into the atmosphere.

Where is 90 percent of the earth's population?
developing countries
What is pi squared times the diameter of the sun times the population of earth?
An utterly meaningless number. Among other problems, the population of Earth is constantly changing and you didn't specify the length units to be used for the diameter of the Sun (which also isn't exactly a fixed quantity). If you're so bored you're asking pointless questions to entertain yourself, why not see if you can find a question you actually know the answer to and answer it? There are entire topics about video games, which is likely about your speed.

Approximately 6,706,993,152, as of July 2008.
Is a pigeon a sign of death?
Of course not. Otherwise the entire population of the earth would be dead.
Why is biodiversity decreasing around the world?
due to over population of humans on earth. Natural resources they consume are leaving animal with nothing to live on.

Can the population of the earth fit in Connecticut?
No, the population of the Earth is currently around 7.8 billion people, while Connecticut has a population of approximately 3.6 million. Therefore, the entire global population cannot fit within the borders of Connecticut.
What are the two allotropes of oxygen?
The two allotropes of oxygen are O2 (dioxygen) and O3 (ozone). Dioxygen is the most common form of oxygen in the Earth's atmosphere, while ozone is a less common form found in the stratosphere where it plays a crucial role in absorbing ultraviolet radiation.
What are two naturally occurring allotropes of oxygen?
Two naturally occurring allotropes of oxygen are dioxygen (O2) and ozone (O3). Dioxygen is the most abundant form, making up about 21% of Earth's atmosphere, while ozone is found in the stratosphere and plays a crucial role in filtering out harmful ultraviolet radiation from the sun.
How much does the entire population of the earth weigh?
The estimated weight of the entire population of the Earth is difficult to determine as it would depend on factors such as age, size, and body composition. However, a rough estimate would be around 316 million tons.
What will life be like on earth when your star changes into a red giant?
There will be no life on Earth and possible no Earth. As the sun expands the amount of light and heat reaching Earth will increase many times and Earth will becomes extremely hot. The entire surface of the planet will become an ocean of lava. It is likely that the sun will eventually expand enough to consume and destroy Earth.

How much percent of earth's dry land is still available and how much percent is covered with organisms?
Depends on what you mean?Do you mean only on dry land? Or are you asking to include sea life as well?I can tell you about the percentage for the entireEarth's mass, however; meaning it calculates the entire population of the Earth including the sea.The entire Earth's population of living organisms' number fluctuates daily as some organisms only live for a day; but on average, about 76% of the Earth's mass is live organisms. (This is including aquatic life.)
