Kociara created the petition after she heard that the event was to be held at SeaWorld. Kociara told The Dodo that her kids, ages four and five, love "Sid the Science Kid."
"When we found out that he was going to be at SeaWorld, my kids were the ones who wanted to protest it," she said, adding that her kids think that whales and dolphins "should live in the wild, not in a tank."
Interestingly, PBS has dealt with the issue of cetaceans (whales and dolphins) in captivity before. In 1997, its television series Frontline published a breakthrough investigation into the industry of marine parks like SeaWorld. The report was one of the first major news stories to cover the story, and sparked a movement that has led to the surge of backlash against cetacean captivity that's exploding today.
