2. Crowded Slums
With the globe’s population tipping over 7 billion and a shift from rural to urban lifestyles, more and more people find themselves living in impoverished squalor. UN-Habitat estimates that 33% of the urban population in the developing world are slum dwellers. These segregated shanties suffer from overcrowding, substandard shelter, inadequate infrastructure, poor sanitation, rampant crime and fast-spreading disease. Rio’s hillside favelas are now a bit of a tourist attraction where visitors pay for guided “slum tours” of how the other half live. It brings awareness to the problems, but makes a spectacle of the inhabitants.
