Permian Extinction and Geological Processes

The video explores mass extinctions, focusing on the Permian extinction, known as 'The Great Dying.' It discusses the Siberian Traps' volcanic activity as a potential cause, highlighting the role of magma and greenhouse gases. The video concludes with evidence supporting this hypothesis and invites viewers to support the channel.
