More than 800 million people in India are considered poor. Most of them live in the countryside and keep afloat with odd jobs. The lack of employment which provides a livable wage in rural areas is driving many Indians into rapidly growing metropolitan areas such as Bombay, Delhi, Bangalore or Calcutta. There, most of them expect a life of poverty and despair in the mega-slums, made up of millions of corrugated ironworks, without sufficient drinking water supply, without garbage disposal and in many cases without electricity. The poor hygiene conditions are the cause of diseases such as cholera, typhus and dysentery, in which especially children suffer and die.
