==== These community groups are transforming Rio de Janeiro into a Sharing City ====
Rio de Janeiro is a city of extremes. Inequality is rampant, and while a small elite enjoy the "luxury" of housing, high quality education, and concentrated public funding, the majority of its citizens share the rest. The best examples of sharing are born not out of excess but from scarcity and collective problem solving. How do you build a house without money? How can you study if you can't afford to pay for a bus to class? How can a farmer survive with no land? How can people without access to resources reasonably start up a working business? And of course – how can people help each other stay safe?
