This video is called The Salt of the Earth / Le Sel de la terre (2014) – Trailer English Subs.
On 1 January 2015, I saw the film The Salt of the Earth.
Salgado was born in a ranching family. His father wanted him to study law. He did not like that, and switched to studying economics. After a few years of work as an economist, he decided that he really wanted to be a photographer.
Meanwhile, he had fled from the brutal dictatorship ruling Brazil then. He traveled to many countries, making ‘social photography’ about humans and their lives.
Sebastião Salgado saw human beings during terrible circumstances: during wars. In Croatia, Salgado tells, nationalist paramilitaries killed many Serbs in the Krajina region and made many others refugees. In Bosnia, there was violence against Muslim civilians. Then, the horrors of genocide in Rwanda.
The deaths, and more deaths, became too much for Salgado. How could he continue to make photographs? His father’s ranch provided the answer. When Sebastião had been a child, large parts of it were Atlantic forest. Water, birds, and other animals everywhere.
Now, decades later, erosion had destroyed much. Sebastião’s father deplored the erosion, but did not know what to do against it. Then, Sebastião’s wife inspired her husband to start re-planting many Atlantic forest trees in the soil which had dried out.
This 2012 video says about itself:
Instituto Terra is a civil non-profit organization, founded in 1998 by Mrs. Lélia Deluiz Wanick Salgado and Mr. Sebastião Salgado, headquartered at the Bulcão Farm, in Aimorés, State of Minas Gerais, in Brazil, that intends to promote, facilitate and support programs and activities of fostering ecologically sustainable development by recovering, conserving, and correctly using natural resources. Following this purpose, Instituto Terra has been operating in four areas: environmental recovery, environmental education, nursery, and the encouragement of sustainable rural development.
The success of Instituto Terra inspired Salgado to photograph again. This time, many landscape and wildlife photographs. Eg, the film shows him making walrus photographs on Wrangel island in Arctic Siberia.
