Earth’s Oxygen Won’t Last Forever?!

Turns out, our breathable air is on borrowed time! Scientists say Earth’s oxygen-rich atmosphere will eventually vanish, making way for a methane-heavy world where most life (including us) can’t survive. The wild part? This could happen way sooner than the sun frying us—like, in a billion years. So, if we want to stick around, we might need a Plan B planet. Also, this changes how we look for life on other worlds—maybe oxygen isn’t the only sign to watch for! #EarthScience #FutureOfEarth #SpaceTalk #Science
