Mass Extinction Causes that Nobody Talks About! (& Addressing Comments ;) | GEO GIRL

I recently posted a video about the Top 3 Mass Extinction causes (   • The Major Causes of Mass Extinction E...  ), and I got a lot of comments on that video mentioning other potential causes. In this video, I talk about all the lesser known mass extinction causes and I address a lot of the comments from that previous video. The top 3 I discussed in the previous video include global warming, CO2 increase & associated ocean acidification, and ocean anoxia. The other non-top 3 but still quite devastating causes of mass extinctions include SO2 and ash-caused global cooling, SO2 and CO2 caused acid rain, HCl and HF caused acid rain, Cl and CH4 caused ozone destruction, toxic substances like Hg or H2S released by volcanos or produced by bacteria during ocean anoxic events, and astronomical effects like nearby supernovae or gamma ray bursts. I hope you enjoy learning about what triggers these conditions and how they affect life on Earth during mass extinction events!
