«Todo cambia» – means «Everything is changing» in Spanish. Also it is the famous song of Argentinian national singer Mercedes Sosa, who was banned and persecuted during the period of civic-military dictatorship in this country (1976–1983). At this time, as a result of the state-delivered violence, between 10,000 and 30,000 people were killed or disappeared.
During my residency in Argentina, I visited the Costanera Sur ecological reserve in Buenos Aires, which stands on the river La Plata, neighbouring the luxury skyscraper district Puerto Madero. This is a wonderful area of wild nature right next by the roaring megapolis, representing the rich biomes of the «pampas» grasslands, wetlands and river coast, full of birds, plants and insects to peacefully observe – and a perfect place for joggers and cyclists, couples and families, birdwatchers and regular tourists to spend their day.
Though, it is also a place that keeps the memory about the tragic events of Argentina's near past. It was artificially made in the late 70s when the military government launched the project on the motorways construction. To complete it, many streets with the old private households in several Buenos Aires districts were demolished, and the debris from these buildings was thrown into the river. Rio de la Plata itself has witnessed a lot the crimes of the dictatorship – when many of the kidnapped people, among whom were students, artists, intellectuals and literally every person who was suspected of being left-wing activist, were executed by pushing out of the aircrafts flying above the river and then found dead from hitting water or drowning.
But the nature absorbed this new piece of land, all consisting of debris that used to be people's homes, and it became a part of the landscape. During the decades, trees and grass have been covering it with their green, and the tides have been smoothing the bricks, slowly wiping out all the memories about that tragic events and people's deaths and lives. Today those who don't know the background behind this place, would never even recognise it as something made artificially. And only if you take a closer look, you will be able to notice these remains of history among the grass, water and sand, to distinguish them in the surrounding landscape.
