This issue of Environmental Practice is devoted to water resources. Water issues, including water quality and supply, are projected to be the global geopolitical hot button issues of the twenty-first century. While much media attention has been paid to water shortages in states like California and Arizona, the Great Lakes, representing 20% of the world's fresh water supply, are also under threat. Peter Annin's 2006 book, The Great Lakes Water Wars, provides a cogent discussion of how competition for Great Lakes water resources is likely to play out. He notes that at the time of the writing of the book, water quality and invasive species including the zebra mussel had been the chief concern in the Great Lakes. Invasive species is still of great concern, as witnessed by the attempts to prevent invasive Asian carp from entering Lake Michigan via the Chicago Area Waterway System (CAWS). However, attention has shifted from invasive species to the issue of water supply and quality. Annin states: "Water scarcity throughout the world-and even in parts of the Great Lakes region-will put mounting pressure on one of the most abundant freshwater ecosystems on earth.... The lakes are the region's most important and precious natural resource-they define the area's economy, culture and environment." The debate and tension among water-parched states over access to Great Lakes water resources will no doubt provide some great political theater in the coming decades and could ultimately lead to major changes in water resource policy at the local, state, and federal levels. Stay tuned! Water resources and Great Lakes issues will be two of many exciting tracks at the 2016 NAEP annual conference, April 11-14 in Chicago. We hope you will be able to attend.
