A multi-disciplinary panel, held at the Shedd Aquarium, provided a public examination and discussion of the threat of Asian carp to Chicago and the Great Lakes. Experts in biology, economics and policy shared the most up to date information about how these species threaten the ecology of the Great Lakes, how closing Chicago waterways would affect the regional economy, and the broader implications for the Great Lakes region and environmental management. Cosponsored by the Program on the Global Environment and the Chicago Council on Science and Technology.
