Oxygen can be consumed by a chemical reaction, such as fire, in which case the oxygen is not destroyed but becomes part of another substance.

All of earths resources will be destroyed and the trees will die out. Once all the trees die out, the people will not get any oxygen and we will all die.
Strangely enough the world has already gotten through severe pollution related changes. Originally the earth had a reducing atmosphere (one without oxygen) as photosynthesis became more popular among life forms the content of oxygen rose destroying the environment for anaerobic organisms. Oxygen was in this case a pollutant. In today's world ithe levels of pollution will never reach a stage where all life is destroyed - something will be left that can take advantage of the new environmental conditions. We may not survive, life will. So the world will not be destroyed - just us.
They are destroyed by weathering after exposure to the surface.

Ozone is destroyed by the CFC gases. CFC converts ozone to oxygen.

the enzyme who does it is destroyed by oxygen
No. Atoms cannot be destroyed by chemical processes. When iron rusts it bonds with oxygen to form iron oxide.
Animals homes are being destroyed, droughts and oxygen loss
Typically, that substance becomes oxidized.
An anaerobe is an organism that thrives in an environment without oxygen. Facultative anaerobes prefer an oxygen-free environment but can survive in the presence of oxygen. Obligate anaerobes are destroyed by oxygen and cannot survive if it is present in their environment.
Anaerobic. They do not grow in the presence of oxygen, and hydrogen peroxide releases oxygen.
Since matter cannot be created or destroyed you cannot "make" oxygen. However, you can extract it from de-ionised water through electrolysis.
