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.

According to organizers, hundreds of thousands of environmentalists and other activists participated in marches in 436 cities and 52 countries on May 25 to protest the Missouri-based biotech giant Monsanto Company, whose products include genetically modified (GM) seeds and the glyphosate-based herbicide Roundup. The global March Against Monsanto generated events in countries including Australia, France, Germany, the Netherlands, Spain, the UK and the US.

Col. Alberto Julio Candiotti, a former Argentinian military officer who was wanted for crimes committed during the country's 1976-1983 "Dirty War," was arrested May 23 in Montevideo, Uruguay. Information for the whereabouts of the 68-year-old, who was residing in the city with his wife, was valued at 100,000 pesos (USD $20,000). The former officer was arrested by Uruguay's National Police. Authorities are currently uncertain whether Candiotti sneaked into the country or falsified documents to gain admittance.

Former Argentine dictator Gen. Jorge Rafael Videla (1976-1981) died the morning of May 17 in the Marcos Paz prison in Buenos Aires province, where he was serving a 50-year sentence for crimes against humanity. He was 87. Videla led the coup that removed then-president Isabel Perón from office on Mar. 24, 1976 and started a period of military rule that lasted until 1983. Videla himself was made de facto president on March 29, 1976 and held the office until March 1981, when he was replaced by Gen. Roberto Viola.

The death of former Argentine dictator Gen. Jorge Rafael Videla (1976-1981) on May 17 brings to seven the number of Latin American and Caribbean de facto heads of state who are now in prison or facing criminal charges for their acts while in power. All but one were charged in the last decade.

Some 200 to 300 agents of the Buenos Aires Metropolitan Police invaded the grounds of the José T. Borda public psychiatric hospital in the Argentine capital during the early morning of April 26 to guard demolition workers as they bulldozed one of the hospital buildings. When hospital workers, patients and community members gathered later to protest the demolition, police agents used nightsticks and rubber bullets against the crowd. Protesters said some 50 people were injured, including at least 10 patients, seven nurses, three media workers and a member of the city legislature, María Rachid. The authorities reported 36 people injured, 17 of them police agents. Eight people were arrested.

The Appeals Court of Copiapó province in Chile's northern Atacama region issued an order on April 10 completely suspending work at the massive Pascua Lama facility, an open-pit gold, silver and copper mine under construction in the Andes on both sides of the border between Argentina and Chile. The order was in response to a complaint filed by five communities of indigenous Diaguitas in the Huasco Valley; the residents charged that the work was damaging the Toro 1, Toro 2 and Esperanza glaciers and contaminating water resources in the area, according to Lorenzo Soto, the communities' lawyer. The Chilean government's National Geology and Mining Service (Sernageomin) and the Environmental Evaluation Service have also found environmental damage from the project. Construction is about 40% complete at the mine site, which is under the control of the Toronto-based Barrick Gold Corporation.

As of April 1 the Environmental Evaluation Service of Atacama, a region in northern Chile, had imposed a new fine on the Chilean subsidiary of the Toronto-based Barrick Gold Corporation for violations at its Pascua Lama facility, a giant open-pit gold, silver and copper mine being built in the Andes at the border between Argentina and Chile. The fine on the subsidiary, the Compañía Minera Nevada SPA, came to about US$85,509 (expressed as 1,000 Monthly Tax Units, UTM, a special unit Chile uses for mining taxes and fines; it is set this month at 40,125 pesos). This was in addition to a US$256,518 (3,000 UTM) fine the service imposed a month earlier. According to Pedro Lagos, Atacama's regional minister for the environment, the fines are for the company's failure to meet requirements for monitoring damage the mine's construction could cause to nearby glaciers.
