TripAdvisor will no longer sell tickets to attractions that breed, import or capture whales, dolphins, porpoises and other cetaceans for public display, the company announced on Wednesday.

The move will ban sales to attractions and events at parks and aquariums worldwide, including SeaWorld, which has locations in Florida, Texas and California, Loro Parque in Spain and the Georgia Aquarium.

The policy is the latest addition to TripAdvisor’s 2016 animal welfare policy, which ended sales of tickets to experiences where travelers have physical contact with captive wild animals, such as elephant riding and tiger petting.

The policy, which includes the TripAdvisor subsidiary, Viator , comes a year after the company banned sales of tickets to performances and shows considered demeaning to animals, and it comes as concerns increase over animal tourism and animal welfare.
