The Permian-Triassic Extinction Event

The Permian-Triassic Extinction Event, about 252 million years ago, was Earth's most severe mass extinction, wiping out around 90-95% of marine and terrestrial species. It was likely caused by a combination of intense volcanic activity, climate change, and ocean acidification, which drastically disturbed ecosystems. The massive volcanic eruptions released vast amounts of greenhouse gases, leading to extreme global warming, acidifying oceans, and depleting oxygen in the water. This catastrophic event took millions of years for life to recover and dramatically reshaped the course of biological evolution on Earth.
