First question that comes to my mind is, if kids and adults wants to learn or be educative about certain animals why cann't they do so in natural habitat of these animals instead of artificially creating a zoo or aquarium and making thier survival difficult.
Am being thinking about this since https://www.iht.com/articles/ap/2007/12/01/america/NA-GEN-US- Aquarium-Whale-Death.php
Leave them alone and arrange safari's / boat rides / under water scuba for folks interested... for educational purposes ...
