TripAdvisor, a leading travel website, says it will no longer sell tickets to attractions where tourists come into contact with wild animals or endangered species. The policy change includes, but is not limited to, elephant rides, "swim with" activities involving the touching or riding of dolphins, and the petting of captured wild animals such as tigers. The company also announces that is developing an educational portal, with the aid of several wildlife protection groups, to inform tourists about animal welfare practices.
