Robert M. La Follette School of Public Affairs Policy Goals • Ecological responsibility • Prevent economic damage by AIS • Preserve economic vitality of Milwaukee • Political feasibility
Policy Recommendations • Support strong but flexible national regulation on ballast water • Do not support closing the Chicago Locks as a sole means of controlling Asian carp • Collaborate to secure funding for AIS management • Use media attention to educate public Robert M.
