It was the production of oxygen that led to the first atmospheric pollution event, as the metabolised free oxygen became more dominant in the atmosphere. It was this which gave rise to the so-called Cambrian Explosion; oxygen is like rocket fuel for life and allowed for multicellular organisms to evolve.
Of course I may have butchered the scenario somewhat, but it's essentially correct.
Not technically correct.
The first oxygen producing bacteria evolved >3 billion years ago, while the great oxidation event that resulted in accummulation of free oxygen in atmosphere occurred >2.5 billion years ago. But first indications of multicellular organisms occurred > 3 billion years ago. So oxygen in atmpshere didn't allow multi-cellular organisms to evolve. Pre-oxidation atmopshere clearly already allowed multicellularity to evolve, not just once, but many times.

Yes. But soon the primordian hydrogen and helium atmosphere was replaced by a nitrogen and carbon dioxide atmosphere that resulted from volcanism on the young and still mostly molten ball of rock.
Guess, what, carbon dioxide has oxygen in it.
Once there is chemically combined oxygen, there is ingriendients for biological processes such as photosynthesis to extract that oxygen from the carbon and release it to the atmosphere, like the little house plant you might have in you home still does every fucking day.............
