In 2015, Spanish environmentalists posted a video showing a dolphin trainer mistreating animals at the dolphinarium in Mallorca. It prompted an international scandal, because the trainer in question was José Luis Barbero, who had just been appointed as vice president at the prestigious Georgia Aquarium in Atlanta in the US.

On one side stands the lucrative entertainment industry, which treats intelligent animals as valuable commodities.
