The Brazilian Amazon rainforest famously houses the ‘most isolated man on the planet’, supposed to be the last remaining member of an un-contacted tribe. As of 2007 the government enforced a 31 square mile radius around him as a ‘no logging zone’. Although he is safe from developers who

may wish to destroy his forest, the man is thought to live in complete isolation (attempts to contact him have led to an agent getting shot with an arrow). Although others in Brazil obviously don't live in such extreme solitude, there's a surprising rise in the numbers who now opt to live alone. Although this choice to go it alone demonstrates an increasing percentage of the population are enjoying financial independence, there have been negative consequences for the infrastructure (as consumption of water and energy increases).
