Hello @sirenahippie thank you very much for your comments! Everything you say is respectable, I really understand your point of view, actually, this post is written from the point of view of the dolphinariums in Mexico where he had the opportunity to work on some scientific work. One thing that is certain is that human beings have deteriorated their natural habitat (pollution and above all, excessive fishing) so that the average life under human care almost triples what they can live in the wild. Greetings and I appreciate your comments!😁🐬
