Natural gas drilling noise correlates with 50 percent sage grouse decline

Evidence

One study has documented sage grouse population declines of as much as 50 percent downwind from deep natural gas drilling rigs in Wyoming. Though factors such as chemical pollution may also be at work, the prime suspect is noise: 70 dBA at a quarter-mile away. — Gordon Hempton, John Grossmann, One Square Inch of Silence- One Man’s…, 975
