Muriel Arnal saw the suffering of exploited animals from a very young age when she discovered small circus zoos. Her admiration of the fight to save the gorillas and their natural habitat led by Dian Fossey as well as her meeting with Théodore Monod, who would be a supporter of the association, led her to create One Voice in 1995 for the ethics of animals and the planet
Having lived abroad, the participation of the association in big international coalitions was obvious to her: on animal experimentation (ECEAE), on fur (Fur Free Alliance), on dolphinariums (Dolphinaria-Free Europe)
One Voice protects individuals, with a vision of uniting in our fights: for the animals, for humans, and for nature.
