Canada's Wind Farms

http://www.freep.com/article/20100226/NEWS06/2260374/storm-brews-over-ontario-winds
The title of this site is Will Canada's Wind Tribunes Invade Lakes
The site was about how canadas wind farms were effecting lakes and the city where we live.
Some pros of canada's wind farms are they give green energyand boost the quality of recreational fishing. Some cons of Canada's wind farms are they are ruining the views on houses on the lake, bird migration and are making the shoreline homes drop in prices. I don' t believe that Canada should go on with this process because its making cities near Lake St. Clair and the Great Lakes lose money on houses that had beautiful views very hard to sell because the wind farms are blocking them making our city economies worse. What i could do as a citizen to fight the plan would get a group of people who know a lot about these wind farms to go to Canada and make a deal with the Canadians to take them down or not put them in the middle of the lakes .
