This episode of the Green Interview features Marina Aizen, one of Argentina's most distinguished journalists, who served for many years as United Nations correspondent for a major wire service. Among the stories she covered was the 1992 Environmental Summit in Rio de Janeiro, and that, she says, is where she "got hooked on environmental stories." She recently completed a book on the Mendoza case: the remarkable legal action that lead the Supreme Court of Argentina to order and enforce a comprehensive rehabilitation program for the Riachuelo River in Buenos Aires, once identified as the eighth most polluted spot on the planet.
