And Why It matters
Dr. Francine McCarthy, Geology Professor and Chair of the Department of Earth Sciences at Brock University, Ontario, Canada
Dr. Francine McCarthy, a geology professor and Chair of the Department of Earth Sciences at Brock University in Ontario, Canada, has spent her career researching geological evidence of planetary change. Her recent research at Crawford Lake in Ontario has produced evidence through the lake’s layered sediment that human impact has changed the Earth, leading us into a new geological period or epoch: the Anthropocene. McCarthy notes that by strict convention we are still living in the Holocene – but is this societally relevant and does it accurately describe our planet today?
