We are causing a sixth Great Extinction

Curtis Marean, professor and associate director of the Institute of Human Origins at Arizona State University, Scientific American, 2015: As we moved out of Africa about 70,000 years ago and colonized the planet, “everywhere Homo sapiens went, massive ecological changes followed. The archaic humans they encountered went extinct, as did vast numbers of animal species.”

This was especially true of large mammals.  Ecography: “Our world has lost most of the large terrestrial animals present 100,000 years ago.” …“human colonization was the dominant driver of megafaunal extinction across the world.”
