Gill speaks to PNAS about the Anthropocene

PNAS interviewed Jacquelyn Gill, associate professor of paleoecology & plant ecology with the University of Maine School of Biology and Ecology and Climate Change Institute, about defining the Anthropocene, a proposed geological epoch dating from the commencement of significant human impact on Earth’s geology and ecosystems. “It’s challenging to agree on a start date for the Anthropocene. Any one choice almost seems arbitrary,” Gill said.
