Since 2017, 115 North Atlantic right whales (NARWs) have been documented dead, seriously injured, or sporting sublethal injuries and illnesses. Scientists refer to this phenomenon as an unusual mortality event, and assert that entanglement and vessel strikes are the leading causes. Fewer than 350 NARWs remain, and it is estimated that only one-third of their deaths are documented. Experts claim that only “quick and decisive action from humans” can ensure the species’ survival. Some proposed regulations will affect where and how the relevant fisheries are able to operate.
