From the Salt Lake Tribune:
One summer, over a decade ago, biologists discovered that gray wolves – once driven to near-extinction in the continental United States – were breeding again in Washington state. The sound of howling wolf pups was welcome news for conservationists, but not for the state’s current $700 million cattle industry. Not long after, when some wolves began to prey on livestock, age-old tensions were resurrected. Some members of that first pack were poached – despite federal protections.
