Future without oxygen: Earth's looming atmospheric crisis

The article from MSN discusses a potential future environmental crisis where Earth's oxygen levels could significantly decrease, leading to an atmosphere inhospitable to most current life forms. It explores the concept of "anoxic events," historical periods where oxygen levels plummeted due to various geological and biological processes. The piece highlights how human activities, like deforestation and the burning of fossil fuels, might accelerate such an event by altering the balance of oxygen production and consumption. Scientists are studying ancient geological records to understand these past events better, aiming to predict and possibly mitigate future oxygen depletion. The article also touches on the potential for microbial life to thrive in low-oxygen conditions, suggesting that while complex life might struggle, simpler life forms could adapt. This looming atmospheric crisis underscores the need for sustainable practices to maintain Earth's delicate atmospheric balance.
