Whales and dolphins 'should have legal rights'
Campaign for intelligent marine mammals to have right to life, which would protect them from hunters and captivity

Campaigners who believe that dolphins and whales should be granted rights on account of their intelligence are to push for the animals to be protected under international law.
A group of scientists and ethicists argues there is sufficient evidence of the marine mammals' intelligence, self-awareness and complex behaviour to enshrine their rights in legislation.
Under the declaration of rights for cetaceans, a term that includes dolphins, whales and porpoises, the animals would be protected as "non-human persons" and have a legally enforceable right to life.
If incorporated into law, the declaration would bring legal force to bear on whale hunters, and marine parks, aquariums and other entertainment venues would be barred from keeping dolphins, whales or porpoises in captivity.
"We're saying the science has shown that individuality, consciousness and self-awareness are no longer unique human properties. That poses all kinds of challenges," said Tom White, director of the Centre for Ethics and Business at Loyola Marymount University in Los Angeles.
"Dolphins are non-human persons. A person needs to be an individual. And if individuals count, then the deliberate killing of individuals of this sort is ethically the equivalent of deliberately killing a human being. The captivity of beings of this sort, particularly in conditions that would not allow for a decent life, is ethically unacceptable, and commercial whaling is ethically unacceptable,"
