Wind turbine threat to bat populations costing farmers billions each year

Daily Mail
"Thousands of bats have been killed by wind turbines causing a population decline that could cost the farming industry billions each year, experts claim.The nocturnal creatures are welcomed by farmers across the world as they eat large numbers of insects that usually damage crops.This reduces the amount that farmers have to spend on pesticides and saves millions of new plants that could be obliterated by the creepy crawlies.But it is believed that bats and similar species are being killed 'in unprecedented numbers' by the enormous rotor blades of wind turbines.Thousands of dead bats have been found near wind farms, and some scientists believe sudden changes in air pressure close to wind turbines can cause the lungs of the tiny creatures to collapse."
