Who are we?

Mata’i Souchon is the director of La question aquatique, the French association that has organized World Day for the End of Fishing and Fish Farming and World Day for the End of Speciesism since 2019. He is also the president of Les Estivales de la question animale, a networking event for activists that notably contributed to the creation of the L214 association and the Parti animaliste. Involved in the animal cause since 2013, he co-founded Césama, a think tank working on macroeconomic scenarios to redirect agricultural subsidies towards support programs for farmers transitioning to plant-based production. He also led the Réseau Sentience for ten years, a network of student associations working to initiate cultural change in favor of animals and to help students pursue careers in animal advocacy.

A donor and activist for the animal cause, Joseph Ancion is responsible for coordinating the World Days, promoting their goals on social media, and maintaining communication with partner organizations. He is also a board member of the Paris 8 branch of the Réseau Sentience. He is particularly interested in the impact of artificial intelligence on non-human animals.

Antoine Doljac is a student at Sciences Po Paris. A civic service volunteer with the World Days team since April 2025, he contributes to event coordination and content writing for communication materials. Interested in the intersections between activism, media, and the animal advocacy sector, he helps promote the themes of the World Days to new audiences.

Yves Bonnardel, an egalitarian grassroots activist, is one of the main founders of both World Days, where he has served on the association's board since 2015, contributing to their strategic direction. His commitment to animal equality dates back to the origins of the contemporary movement in France, as a long-time contributor to Les Cahiers antispécistes, a major theoretical and activist journal that launched the movement in 1990. He has supported the development of numerous initiatives, including the Veggie Pride march, Les Estivales de la question animale, and the Swiss association Pour l'Égalité Animale. He founded the Réseau contre le spécisme and World Day for the Abolition of Meat, which later became the Marche pour la fermeture des abattoirs. He also co-founded éditions tahin party and the antispeciesist journal L’Amorce. He is the author of numerous theoretical and strategic articles and two books on the animal question (La Révolution antispéciste, Presses universitaires de France, 2018, and Solidarité animale. Défaire la société spéciste, La Découverte, 2020).
