The most devastating extinction event in Earth's history occurred approximately 252 million years ago, marking the end of the Permian period. Known as the "Great Dying," this event wiped out about 96% of all marine species and 70% of land species, making it the most severe mass extinction ever recorded. Scientists believe that massive volcanic eruptions in what is now Siberia released enormous amounts of carbon dioxide and methane into the atmosphere. This led to extreme global warming, ocean acidification, and a breakdown of Earth's ecosystems.
As temperatures rose, the oceans became depleted of oxygen, creating deadly conditions for marine life. On land, forests were destroyed, and most large animal groups were driven to extinction. This catastrophic event took millions of years for life to recover from, but it eventually paved the way for the dominance of the dinosaurs in the Triassic period. The Permian-Triassic extinction serves as a stark reminder of how environmental changes can drastically reshape the planet’s biodiversity.
