The atmosphere was changed from being a reducing one to an oxidizing one. Then, the most important change was regarding the relative concentration of molecular oxygen, which is thought to have incremented a thousand times. Concomitantly the ozone layer also formed.
Photosynthesis converts carbon dioxide into oxygen. Therefore, much of the oxygen in our atmosphere is present due to photosynthesis.
