Answer 5

Oxygen will last as long as bacterial organisms are alive.  The oceans are alive with organisms that produce oxygen.  The atmosphere is currently made up of 19% oxygen by volume.  In comparison, carbon dioxide (CO2) makes up only 380 parts per million by volume (0.0380%).  In other words, we have a lot more oxygen than CO2.  Global warming is caused by the increase of this small percentage of CO2.

As long as plants are around there will be oxygen.
