Lake Invaders The Fight For Lake Huron Dvd

Lake Huron, one of the five parts comprising the Great Lakes, has been hit with over 180 exotic species invasions over the last century. Each invasion changes the ecosystem in ways we can't predict. Fish populaitons have collapsed, the entire food web completely altered, and a multi-million dollar industry has dried up. Biologists are racing to understand these changes and restore balance to the third largest lake in the world before the next invader arrives.
