Book Summary: The Sixth Extinction, by Elizabeth Kolbert


In this “Unnatural History”, the author chooses the setting of a small island of the Italian coast to show how climate change is happening and an imminent threat. She says that since the Industrial Revolution, we have burned some 365 billion metric tons into the atmosphere. She also talks about ocean acidification. As CO2 is added to the ocean, it becomes more and more acidic. This effects what fish can live in those waters. In conclusion, the author is strongly stressing that ocean acidification is a big issue and that it is one of the largest and most drastic.
