Turbines Bad for Birds

I decided that this is another article that is important to add because of it's look at possible negative impacts by green tech. Although short, the article suggests that wind turbines could be a legitimate threat to birds. If it's true that it kills birds it could be a solution that's not worth the cost.
It's a coincidence that I found two articles with eco-friendly criticisms which I think says a lot. Perhaps more is coming to light about the bad side of this generally praised Green trend.
