Students selected Knute Nadelhoffer, professor of ecology and evolutionary biology and director of the University of Michigan’s Biological Station, to address attendees and explain the significance of Earth Day. He spoke from the steps of Hatcher Graduate Library to the crowd.
Nadelhoffer spoke to the intentions of Gaylord Nelson, the former Wisconsin senator who founded the day in 1970, whose wish was to raise awareness about a multitude of environmental issues, including pollution and the impact of overpopulation on the environment.

Our challenge is to adapt to these changes and to work to prevent more severe climate change by weaning ourselves from fossil carbon energy."
