The Sixth Extinction
by Elizabeth Kolbert
A process in which the Earth’s oceans absorb carbon dioxide and quickly becomes more acidic, endangering the survival of many marine species, including coral. Because it is caused by the absorption of carbon dioxide from the atmosphere into the ocean, it is directly impacted by the increase in atmospheric carbon dioxide that is a result of humanity’s consumption of fossil fuels.

Explanation and Analysis:
In Chapter Six, Kolbert explores one specific aspect of the environment in which humans have played a major role: the acidity of the oceans. By emitting billions of tons of carbon dioxide into the atmosphere, humans have caused the oceans to absorb larges quantities of carbon dioxide; as a result, the oceans have become considerably more acidic since the dawn of the industrial Revolution, when humans began burning large amounts of fossil fuels, such as coal and gasoline. Because the oceans are becoming more acidic, certain creatures, known as calcifiers—i.e., marine creatures such as barnacles, clams, or oysters, who have Dolorem et quae. Exercitationem non aut.
