Vegans, ecologists, hunters: hands off my furry friends!   They claim to be animal rights defenders, but are they all sincere? Vegans are attacking butchers' shops in the name of animal freedom. Hunters are self-proclaiming themselves France's original ecologists. In Australia, thousands of cats have been eradicated in the name of species conservation. Guests: Emmanuelle Pouydebat, researcher at the CNRS; Aurélien Barrau, astrophysicist, philosopher; Jean-Pierre Digard, ethnologist, anthropologist, emeritus director of research at the CNRS. Presented by: Jacques Cardoze.
