Chapter 5 -- Jennifer E

 On page 107 of The Sixth Extinction an Unnatural History it’s states, “The importance of this discovery is difficult to overstate; had it not been made- and has the chemicals continued to be widely used-- the ozone ‘hole’ that opens up every spring over Antarctica would have expanded until eventually it encircled the entire earth.” This shows that expanding holes on the ozone can cause a severe issue that’ll eventually impact the whole world and possibly cause all humans to die. (E) This is a reason why Paul Crutzen supported calling the new age that humans occupy to be “Anthropocene.” This reveals that Paul Crutzen and his colleagues believe that humans will cause a massive extinction. This overall connects to the larger theme that Humans have had an impact on the environment for millions of years. This quote perfectly matches with this theme because Paul Crutzen believed that humans are going to cause an human extinction or the “end of the world” because of actions like fertilizing plants.
