The Argentine branch of international environmental organization Greenpeace marked World Environment Day—a UN-sponsored event held each June 5—with a protest highlighting damage that the pro-mining policies of José Luis Gioja, governor of the northwestern province of San Juan, could have on Argentina's San Guillermo Biosphere Reserve. Eight Greenpeace activists climbed the Civic Center building in the city of San Juan and unfurled a 20-meter banner with a photograph of a puma and a caption reading: "Gioja: no mining in San Guillermo." The activists were arrested and taken to the central police station.

On May 24 Chile's environmental regulator, Juan Carlos Monckeberg, ordered a suspension of construction at the Toronto-based Barrick Gold Corporation's giant Pascua Lama mine because of violations of environmental laws. He also fined the company $16 million, the largest penalty Chile has ever imposed for an environmental violation. Monckeberg told the Reuters wire service on May 30 that the company would probably require one to two years to make the repairs that would allow it to resume construction.
