When it comes to slums it is necessary to mention the world's top ten cities slums of Rio de Janeiro, Brazil! The term favela has long been used to refer to the worst housing conditions and unsanitary conditions. Of course, when we talk about favelas, we mean places in cities where people live in slums, which contrasts with the urban landscape.
Lines from City of God render the Rio favelas as places where "the devil turns with a sigh". According to an earlier USA Today report, more than 4,000 people are killed each year in Rio's favelas, a rate comparable to a battlefield. If a kid becomes a drug dealer, he'll be in jail within 2 years or dead in the street with a bullet hole in his head.
Brazilians say, "God created the world in six days and Rio de Janeiro on the seventh." Rio de Janeiro is an important gateway to Brazil and even South America, as well as one of the most economically developed regions in Brazil and South America, known as an important transportation hub and center for information and communication, tourism, culture, finance and insurance in Brazil.
Rio de Janeiro's favelas are located on what used to be a barren hill by the sea, where poor people working in the city center chose to make their homes because of the ferries. At the time, there was no electricity or running water on the mountain, and the poor had to go down the mountain every day to carry water for food. Since there was no sewerage, the water was poured everywhere, and when it rained, the roads were muddy and difficult to navigate.
The public **** services and facilities in the slums, such as water and electricity supply, medical care, commerce, education, and security, are far inferior to those in ordinary residential areas. Poverty, backwardness and ignorance make slums a breeding ground and shelter for crime. For this reason, Brazilian government on the one hand, invested heavily in the transformation of slums. On the other hand, it has rounded up triad organizations in the favelas.
