In this episode, Neil DeGrasse Tyson discusses Pangea and how the structure of the old world has affected our world today. Tyson discusses the mass extinction of the ocean around 252 million years ago that killed off 90% of the world. Tyson then describes details of Plate tectonics and how they affect continental drift. Tyson then moves on to explain the “Dinosaur extinction” that killed off the dinosaurs. He ends the video by describing some of the more recent geological events, and explaining the earth is always changing. The earth will continue to change in the future and Tyson believes that we are due for another mass extinction.
This is also one of my favorite episodes be far because of Dinosaurs. Tyson provides a great summary of the earth and how it has changed since its creation. Overall, my favorite parts of this episodes are when he summarizes the Mass Extinction events because I always found those interesting (mainly the Dinosaur extinction). This episode does kind of end in doom and gloom by explaining that another mass extinction event is on the horizon. Overall, it was a great episode.
