Wind Farms Cause More Environmental Impact Than Previously ...

Some will protest it but most prefer the upsides. Wind turbines are like inverse logging, planting super-sized dead tree skeletons with red lights to boot. Environmentalists have tried to save landscapes from much smaller cellphone towers and ski lifts, so it makes no sense that deriving energy from monster machines would wipe out those concerns.
