Visiting the Closest Town to Space (Life with 50% less oxygen)

At this extreme altitude of 5,100 meters, the atmosphere significantly thins and the locals are living with only 50% of the usual oxygen levels. Their bodies have evolved to produce two times more blood cells than ours. On this barren land, not even a single tree can survive because of the low air pressure.

This town in the Peruvian Andes is even 300 meters higher than Mont Blanc, the highest peak in the Alps of Europe.

Far from the modern world, it is a place where crime and danger are always nearby. People come to these harsh lands for only one reason: gold. About 50,000 people have settled here, among piles of trash, all dreaming of wealth.
