Episode 4

This episode was focused on the impacts of comets and asteroids as well as the greenhouse effects on Venus. I thought it was really interesting that humans have actually witnessed some of these impacts like in the Tunguska event. I had always thought that meteorite impacts were a prehistoric phenomenon so it surprised me that we have some written records of large meteor impacts. I also thought it was interesting that Venus used to be a lot like earth but it has experienced a runaway greenhouse effect. It is all the more reason to care about climate change.
