An environmentalist who's been fighting for the protection of Colombia's Atrato River has spoken to FRANCE 24 about why the waterway is vital for the environment and for the local Indigenous community. The Atrato was protected nearly 10 years ago after people got together to persuade Colombia's constitutional court to force the government to take action. Special protections are now in place. But campaigners say the measures do not go far enough. Rodrigo Rogelis, researcher and deputy director of the SIEMBRA socio-legal centre, is currently in Paris to speak at Sciences Po university. He spoke to us in Perspective.
