when did vancouver aquarium get rid of orcas
Vancouver Aquarium For many years, the primary attraction for visitors was the orca show. The Aquarium was the first to capture and display a killer whale, Moby Doll, in a pen at Burrard Drydocks, for 3 months in 1964. Since then, it was home to Skana, Hyak II, Finna, Bjossa, and three of Bjossa's calves. When Finna died and Bjossa was left without other orca companions, the Aquarium attempted to acquire one or more female orcas from other marine parks. However, no suitable companions were found, and Bjossa was moved to SeaWorld, San Diego, in April 2001 where she later died due to a chronic respiratory illness. The Aquarium has since moved to emphasize the educational aspects of the displays rather than the public spectacle of the shows. They have also highlighted their research, rescue and rehabilitation efforts.
Coral bleaching Above-average sea water temperatures caused by global warming is the leading cause of coral bleaching.[2] According to the United Nations Environment Programme, between 2014 and 2016 the longest recorded global bleaching events killed coral on an unprecedented scale. In 2016, bleaching of coral on the Great Barrier Reef killed between 29 and 50 percent of the reef's coral.[3][4][5] In 2017, the bleaching extended into the central region of the reef.[6][7] The average interval between bleaching events has halved between 1980 and 2016.[8]
