Orca displays: A whale of a response
SeaWorld in California is planning to phase out some of its more controversial killer whale shows.
BBC News website readers and people posting on social media sites have been discussing the announcement that 2017 will be the last year of the show in San Diego.
The overwhelming majority of comments are in favour of ending these aquatic displays.
