Favelas are beset by a multitude of problems: poverty, massive unemployment, hunger, malnutrition, inadequate sewage facilities, high infant mortality, low life expectancy and rampant crime. These are the negative effects of over-urbanization. These slums are at breaking point as more and more people flood in from rural areas. Generally the news is bad. It is nice to see that the Rio state government has introduced this pilot project to provide free wi-fi access for 10,000 residents of Santa Marta. The scheme will be extended in due course.
