"The world should not enter the 21st century clinging to archaic 20th century practices. We should shed the mantle of the exploitative and greedy sideshow barker and recognize that teaching whales and dolphins to perform tricks does not showcase their abilities—it exploits them. These circus acts are not educational—they are entertainment. And out-dated entertainment at that. Dolphins do not belong in captivity in the new century. They belong where they have lived for millennia, in the ocean, where their continued presence will motivate us to protect them."
