From Carol Stevenson
If we build wind turbines, they kill birds which fly into them (7 May, p 10). If we don’t build wind turbines, global warming will kill them instead.
So what can we do? Putting lights on the turbines of marine wind farms would make then more visible to migrating birds, especially at night. Painting coloured bars or tips on the blades would make them more obvious when they are turning – and might even turn wind farms into art installations, which could improve their popularity.
