Frustrated fishermen captured video of killer whales thrashing at sea lions in a harbor. Are fisheries being wrongly blamed?

Writer Danielle Clode scoured scientific literature, trying to see if it could really be true that wild orcas would actually cooperate with human whalers.

The growth of whaling in Eden was part of a national trend. In fact, commercial whaling was one of Australia's earliest and most lucrative industries.
