End Seaworld Captivty of Killer Whales

I saw the documentery BLACKFISH its about Killer whales at seaworld and several other sea parks. tilikum and other whales at seaworld killed their Trainers out of furstration. There were clearly upset. They have been kept in small pools and thrown in with other whales who are not their family members or kin to them. The female whales had their calves taken away from them and where clearly showing signs of greif and heartache. Theses are very intelligent mamels. Its a crying shame what is being done to them. Tilikum's dorsel fin was growing sidesways instead of growing upwards. It drooped its is common of male whales in captivity. Please stop this from going on any longer they need your help now. Before its too late. Please see Blackfish. Its on netflicks streaming on in video stores rent it. Or read information online and books.
