Buenos Aires - Half-an-hour's train ride from Buenos Aires lies the suburb of Jose Leon Suarez, with its dirt streets and homes made of wooden planks and scraps of metal.
The path passes by a river containing more rubbish than water. Here and there, the garbage piles up and the stench of burning plastic pollutes the air.
This path leads to the Vicente Catalano Centre for mothers and families.
Gottfried Stein, a correspondent for Germany's ARD radio based in South America, and his wife, Renate, opened the facility in 2007. They obtained funds from the Stuttgart-based International Network of Centres for Mothers and Families, in whose executive committee Renate sits.
