Around 252 million years ago, Earth faced its most catastrophic mass extinction, with nearly 90% of species vanishing. This event was triggered by the largest volcanic eruptions in history, releasing approximately 700 thousand cubic miles of magma and rock. The resulting volcanic gases contaminated the atmosphere and acidified the oceans, while toxic emissions depleted the ozone layer, exposing the planet to harmful UV radiation. Known as "The Great Dying," this crisis nearly eradicated all life. Join scientists as they examine geological evidence and modern ecosystems to unravel how life persevered and diversified into the rich tapestry we observe today.
