( CNN ) -- With a parade of performers already canceling appearances at SeaWorld , now at least one school class says it 's dropping a long-scheduled trip to the park over concerns about the treatment of whales as shown in the documentary `` Blackfish . '' The overnight trip to SeaWorld has been a tradition for fifth-graders at Point Dume Marine Science Elementary School in Malibu , California , for at least a decade , according to Principal Rebecca Johnson , but concerns from parents and students including one determined 10-year-old prompted a decision to go elsewhere on this year 's trip . Although Johnson mostly credited parents for influencing the change , several parents CNN spoke with said 10-year-old Kirra Kotler played a major role in the decision . The girl watched the film `` Blackfish '' with her parents and immediately afterward announced , `` I never want to go to SeaWorld again , '' according to her father , Kirby Kotler . The Kotler family had taken trips to SeaWorld several times , he said . Kirby , 50 , who attended Point Dume the year it first opened , said the entire family was affected by the film but Kirra became especially determined . `` She 's always said she 's going to be a veterinarian , '' Kirby said . `` She 's very passionate about animals .

'' Dave Koontz , SeaWorld 's communications director , also wrote that the theme park believes `` Blackfish '' is misleading and inaccurate . `` It 's disappointing that this year 's class ( from Point Dume ) will not be participating because of the film , '' he wrote . `` Blackfish '' -- which first aired on CNN in October -- traces a 39-year history of killer whales in captivity leading up to the 2010 killing of SeaWorld trainer Dawn Brancheau by the 12,000-pound orca , Tilikum , a whale previously associated with the death of two other people . At least seven entertainers and groups , from the Canadian rock band Barenaked Ladies to country music singer Martina McBride , have canceled appearances at SeaWorld in the wake of `` Blackfish . '' After seeing the film , Kirra Kirby wanted to share it with her friends , her father said . She was determined to get the school to consider other options for the annual trip . 'Blackfish ' sparks debate over taking kids to animal parks . `` She 's very shy , '' Kirby said of his daughter . `` But she finally found her voice . '' Kirby said Kirra launched a word-of-mouth to campaign for the change , in some cases receiving backlash from fellow students who thought she was trying to cancel their overnight trip entirely instead of just changing the destination . Principal Johnson said she is in the process of verifying details for a new trip . Willie Nelson : 'What they do at SeaWorld is not OK '
