Interesting. A few months ago, I remember having a conversation with you about animal circuses and how you would never take your son to one where wild animals are kept, abused for profit and forced to entertain the visitors. And dolphinariums are exactly that. In fact, these types of facilities are being banned in many places around the world because of the increasing pressure from animal rights groups, environmental activists, marine biologists etc. etc. There have even been cases of dolphins and orcas kept in these facilities that attempted to commit suicide by banging their heads against the walls. Marine mammals are extremely intelligent and sensitive animals and they suffer a lot when they are kept in dolphinariums. I know you are a person who likes nature so I believe you just didn´t realize what kind of business you supported by visiting this facility but maybe this friendly (really, no hate) reminder of mine will make you think about it more next time ;) Btw I also recommend that you watch some documentaries about dolphinariums, like for example Blackfish.
