Explore lesser-known causes of mass extinctions in this informative video that delves into the devastating impacts of various geological and astronomical phenomena. Learn about global cooling triggered by SO2 and ash, acid rain from SO2, CO2, HCl, and HF, ozone destruction due to Cl and CH4, toxic substances released by volcanoes or produced during ocean anoxic events, and potential astronomical threats like supernovae and gamma-ray bursts. Gain insights into how these factors affect life on Earth during extinction events, complementing the previously discussed top causes of global warming, CO2 increase, ocean acidification, and ocean anoxia. Discover the complex interplay of environmental factors that have shaped Earth's history and continue to influence its future.
