Exotic Species Feared to Invade Great Lakes

Foreign, or nonnative, species could invade the Great Lakes soon and that would cause significant environmental and economical damage. The National Center for Environmental Assessment gave this warning in a study they conducted. They found 30 nonnative species that pose a threat to the Lakes and 28 other species that are already in the Great Lakes and could spread like wildfire. Feared species of fish include the blueback herring, the monkey goby, and the tench. Some of the busiest ports are potential spots for invading species. These ports include Toledo, Ohio; Gary, Indiana; Duluth, Minnesota; Superior, Wisconsin; Chicago, and Milwaukee. There are already at leats 185 exotic species in the Great Lakes, but only 13 are known to have caused harm to the environment and economy. American and Canadian agencies are already being cautious but it seems that exotic species are still arriving in the Great Lakes. Well, all we can do is hope that nothing happens to the Great Lakes...
