Will we ever run out of oxygen?

How little oxygen Can a human survive on?
Human beings must breathe oxygen . . . to survive, and begin to suffer adverse health effects when the oxygen level of their breathing air drops below [19.5 percent oxygen]. Below 19.5 percent oxygen . . . , air is considered oxygen-deficient.
Can humans make oxygen?
The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air.
Will we ever run out of trees?
While it is possible, it is very unlikely to happen. There are currently over 3 trillion trees on earth. With a net los of ~10 billion trees per year this alone would take 300 years to accomplish. There are also initiatives to replant what gets logged in many parts of the world.
Why are there no trees on the Moors?
When trees were cleared from the uplands, heavy rain washed soil off the hills and into the valleys below, leaving a much reduced mineral fertility and turning the uplands into sodden bleak moors that resist the return of woodland.
What happens if Earth runs out of trees?

By combining it with climate and soil data and excluding areas necessary for human use, they determined Earth could support nearly one billion hectares of additional forest. More than half of the potential forest canopy for new restoration efforts can be found in just six countries.
