Historically, the percentage of oxygen in the atmosphere has fluctuated due to natural factors such as volcanic activity, changes in plant and algae populations, and variations in Earth's climate. Human activities, such as deforestation and the burning of fossil fuels, have also contributed to changes in the oxygen levels, although these changes are not significant enough to have a noticeable impact on the overall composition of the atmosphere at this time.
