We would all die. This is very much unlikely though. Plants take in carbon dioxide and use that, sunlight, and water to produce energy. Oxygen is a waste product of this process. If you are worried about this happening, don't be. It's a proven fact that around 50 - 75% of our oxygen is produced by algae from the ocean. Only 21% of what we breath in is oxygen and of that, only 5% is actually used. The rest is breathed out alongside other gases that pass through our lungs.

Why hasn't all the oxygen on earth ran out?

Oxygen on earth has not run out because green plants release oxygen into the air by a process called photosynthesis.
