North Atlantic right whales face many threats, including entanglement in fishing gear, vessel strikes, climate change—which may alter their migratory patterns and feeding areas—and the impacts of ocean noise on their ability to communicate, find food, and navigate.Threats to whales include commercial whaling, pollution, ozone depletion, global warming an whale watching.
Why are whales decreasing : Once numerous, their populations were decimated during the commercial whaling era. They have been federally protected for decades. Scientists say one reason the whales are now in decline has to do with warming oceans and climate change.

PCBs build up through the food chain, with highest amounts and the worst effects seen in top predators such as whales and dolphins. PCBs are toxic, they cause sterility and are decimating marine mammal populations. Some affected whale populations are set to die out within a generation. "The gray, sei, blue, and fin whale species are not endangered on a global scale, but isolated populations of these species have been severely depleted and face some danger of extinction.
