600,000 birds killed annually...one million bats killed annually..the mosquitoes that carry diseases love these things more that any person on the planet. AND these numbers are just in the U.S. As the old saying goes, "its the cure that kills ya!"

If these links don't work, just google it up. There are dozens of related stories. The environmental groups are nervous and scratching their heads wondering how their support for wind farms has now made them complicit in killing many millions of our precious wildlife. The windfarm planned for Texas that included thousands of windmills was completely scratched because it was predicted that that project alone would kill millions of migratory birds annually. Because of the wind patterns in the region, It would have been ideal for energy generation. Unfortunately the birds have been using the same wind patterns for thousands of years as corridors for their migration to the Gulf and into Mexico. Thank God they cancelled that project or the environmental devastation would have been catastrophic.
Across the globe, you cannot justify killing many millions of birds annually. In a short time it will take a massive negative toll on our planetary eco system.
