What do the Great Lakes of Michigan and the rainforests of Costa Rica share besides a common longitude? We answer that question this week on Sea Change Radio. Each of these places is home to an environmental evangelist who is helping to connect his community to a sustainable future. Sea Change Radio host, Alex Wise, first talks to Ryan King, a biologist, independent journalist, and “eco-preneur” in Costa Rica who has brought biodiesel, biochar and environmental projects to remote parts of the country. Next, Alex speaks to Norman Christopher, Grand Valley State University’s Sustainability Director who’s helping to transform the industrial city of Grand Rapids, Michigan into a cutting-edge, environmentally progressive urban center in the face of tough economic times.
