The Day Oxygen Began to Vanish — Earth’s Deadliest Hour

You wake up one morning and the air feels wrong. Not poisoned. Not burning. Just… thinner. 252 million years ago, Earth came closer to becoming a dead planet than at any other time in its history. In a geological instant, nearly 90% of all life vanished. Oceans lost their oxygen. Forests collapsed. The atmosphere itself began to fail. Scientists call it the Permian–Triassic extinction. But names don’t explain fear. Because here’s the unsettling truth: we still don’t fully understand why it happened — or how close we might be to it happening again. This is the story of The Great Dying. The moment Earth almost stopped breathing.
