Earth's Oxygen crisis: A billion years to seek new horizons

The article from MSN discusses a significant environmental challenge known as the "oxygen crisis," where Earth's oxygen levels are predicted to decline over the next billion years due to the sun's increasing luminosity. This increase in solar energy will accelerate the rate at which oxygen is consumed by weathering processes and other natural cycles, potentially leading to an atmosphere with insufficient oxygen to support complex life forms. The article explores how this scenario might unfold, with scientists estimating that in about a billion years, the oxygen levels could drop to a point where life as we know it might struggle to survive. It also touches on the broader implications for life on Earth, suggesting that humanity might need to consider interstellar migration or terraforming other planets as potential solutions to ensure the survival of life beyond Earth's habitable window.
