Chapter 7 (Jalen Jones)

Chapter 7 begins with Kolbert going to a research center on One Tree Island. She discusses how Great Barrier Reef's job is to protect marine species and food. The Barrier Reef continues to be jeopardized because of pollution. This was tested by scientist Ken Caldeira. Caldeira showed Kolbert that since the 1980's, the reefs have been exposed to high levels of carbon dioxide. This meant that the coral reefs were not immune to the changing levels of carbon dioxide (disagreeing with popular belief). He then said the in the next half century, the reefs are most likely going to dissolve. Going back to theme 4, HUMANS CHANGE EVERYTHING. Fossil Fuels seem to come up a lot in these themes but it needs to be seen that almost everything having to do with human caused extinctions involve fossil fuels. How long is it going to take for people to realize what they are doing?
