The Permian extinction, a cataclysmic event that occurred 250 million years ago, stands as the most devastating mass extinction in the history of the planet. This event, which wiped out 95% of all animal and plant species, was triggered by a series of massive volcanic eruptions in Siberia. These eruptions released vast amounts of sulfur dioxide and carbon dioxide into the atmosphere, causing global cooling and warming, and ultimately leading to the collapse of the food chain. The story of this extinction is a testament to the fragility of life on Earth and the immense power of the planet's geological forces.
