What is the Great Oxygenation Event in Earth's history, and why was it significant?
user
The Great Oxygenation Event, also known as the Oxygen Catastrophe, occurred around 2.4 billion years ago when photosynthesizing bacteria began to produce oxygen as a byproduct, which was released into the atmosphere. This was a significant event because, before that time, Earth's atmosphere had a very low concentration of oxygen and was primarily composed.
