The UK’s Sunday Times recently published this article about potential culling of killer whale populations as a result of their excessive appetite for sea otters.
Orcas used to prey more heavily on other species of whales, such as grey whales; however these have been thinned out considerably by human hunting. Orcas are increasingly feasting on otters, seals and smaller marine mammals, which is having negative effects on population levels.
Pitting species against each other brings up some difficult moral questions. Is it acceptable to kill orcas to save sea otters? Would it be effective? What do you think?
