Best Answer

We need oxygen for our cells to be able to convert food into energy. We breath in order to bring oxygen from the air into our bodies and carry it in the blood to our cells.

Because we practice aerobic respiration we would die without oxygen. Some things, particularly many bacteria, can live without oxygen because they respire anaerobically.
