PBS Newshour Extra, Teacher Resources 7-12gr. SeaWorld will end its orca whale breeding program following growing controversy and protests over the animals’ captivity in recent years. In the announcement, made with the Humane Society, SeaWorld said the orcas currently residing within their facilities will remain in their care, but that the parks’ famous theatrical shows involving the animals will phase out as they cease breeding. Criticism by animal rights activists and the wider public grew after an orca drowned a SeaWorld trainer in 2010. The 2013 documentary “Blackfish” brought even more attention to the subject by examining the psychological effects of captivity on orcas.
