27 Sep 1972–pres. Amazon deforestation▲
The building of the Belém-Brasília Highway in 1958-60 gave farmers access to the Amazon Rainforest, but it was the paving of this route (1974) and the construction of highways into the interior (e.g. the Trans-Amazonian in 1972) which really opened up the rainforest to exploitation. In the following decades, the influx of cattle ranchers, soybean farmers, loggers, and others led to an acceleration in the deforestation of the Amazon Rainforest. Between 1970 and 2015, estimated forest cover in the Brazilian Amazon fell from 4,100,000 km² to 3,331,065 km², although the rate of deforestation has been slowing since 2004. in wikipedia
20 Jun 1973–15 Dec 1983 Dirty War▲
The Argentine military government conducted what it called the “Dirty War”—a campaign of state terrorism in which government forces and right-wing death squads hunted down political dissidents and anybody believed to be involved in leftist activities, ostensibly to destroy the guerrilla threat posed by groups like the Montoneros and People’s Revolutionary Army. Between the 1976 Argentine coup and the restoration of democratic government in 1983, about 30,000 people disappeared; perhaps a third of this number were guerrillas.in wikipedia
11 Sep 1973 Chilean coup▲
In an atmosphere of rising tensions between the right-controlled Congress of Chile and the Socialist government of President Salvador Allende, the Chilean Armed Forces seized control of most of the country in the morning of 11 September 1973; Allende held out until his death early that afternoon during a four-hour battle over the presidential palace (La Moneda). The coup d’état was welcomed by the United States under President Richard Nixon, which had been opposed to Allende and ordered economic warfare and CIA operations against him. In the wake of the coup, Army Chief Augusto Pinochet quickly rose to supreme power in Chile.in wikipedia
11 Sep 1973–11 Mar 1990 Pinochet’s regime▲
Following the 1973 Chilean coup, the Government Junta held power under the Chilean Army Commander-in-Chief, General Augusto Pinochet. Pinochet proclaimed himself President the following year, presiding over an oppressive regime that left over 3,000 dead or missing, tortured over 30,000, and drove some 200,000 Chileans into exile. In 1988, Pinochet, facing eroding support for his dictatorship, was defeated in a popular referendum and made to agree to open presidential elections. As a result he stepped down in 1990, but continued on as Commander-in-Chief of the Army until 1998.in wikipedia

On 25 November 1975—Chilean dictator General Pinochet’s birthday—delegates from Argentina, Brazil, Bolivia, Chile, Paraguay, and Uruguay secretly met in Santiago, Chile. There they established Operation Condor—a clandestine agreement to cooperate in the monitoring and repression of their political opponents. With a joint information center at the DINA (Chilean secret police) headquarters in Santiago, Condor also received support from the United States and other Western nations until it was eventually closed down in the 1980s. The existence of Condor itself did not become public knowledge until 1992.in wikipedia

Although the government agreed to pay for their release, revolts continued and on 17 July 1979 Somoza surrendered power to the Sandinistas.in wikipedia
