How Humans are Causing a 'Sixth Extinction'
By Kevin Caners
We typically think of global warming in terms of the consequences it has for humanity. But it also has huge and troubling impacts on the other species we share our planet with. In this episode we speak with Elizabeth Kolbert about her Pulitzer Prize winning book the Sixth Extinction, and discuss how like the asteroid that killed the dinosaurs, human beings are having an impact so disruptive on the environment, that a large proportion of the earth's species will have likely gone extinct by the end of the century.
