Chapter 4 -- Jennifer E

According to the book  The Sixth Extinction an Unnatural History, on page 86-87 it states, “Owing to the composition of the Yucatan peninsula, the dust thrown up was rich sulfur.

I infer that based our knowledge of the past and by collecting from fossils, it can help us better prepare for the future. This overall connects to the theme biogeochemical systems vary in ability to recover from disturbances. Due to the sulfate covering the sun, it caused a decrease in temperature. If the temperature decreases it can cause some organism to die out.
