摘要

With over 5,500 cubic miles of fresh water and more than 10,000 miles of shoreline, the Great Lakes comprise the greatest single natural resource in North America. The following is an update of Great Lakes issues facing the U.S. and Canada. This compilation covers several issues that could greatly impact the Great Lakes in the coming years. While they seem at first to be separate issues, they are in fact all related. The first topic is a plan to engineer the separation of the Great Lakes from the Mississippi Watershed to help protect the Great Lakes from ecological damage that may result from the invasion of non-native species. Such a project has implications for coastal management, coastal laws, and coastal processes. Related issues are water quality, global warming and changing lake levels. Our understanding of these is all in transition, as noted in the following excerpts. The material does not necessarily represent the personal views of the team who compiled the information; however, it provides the reader with a better understanding of these issues and with the possible changes facing the Great Lakes. Excerpted material is shown in italics.
