They said/say the same thing about birds and windfarms on land. Yeah, the occassional bird gets hit by a blade and dies, it's sad. Not compare that to the millions of birds who die from contaminated air and water pollution? How much wildlife dies when a pipeline bursts or tanker spills? It's a joke that these people hide behind birds when they say they don't like wind farms.

(Also, they've started painting wind blades to make them easier for birds to see. Dropping the rate of bird deaths by an estimated 90%)
