At 16,700 feet high, La Rinconada in Peru is said to be the highest inhabited territory on the planet. It's located near a gold mine, which fuels this city's economy. Just look at the gorgeous mountains in the background - that's quite an awe-inspiring view to wake up to in the morning! But interestingly, this settlement doesn't boast any plumbing or a sanitation system - so unsurprisingly, reports of living conditions are pretty dire.
The only drinking water sources come from lakes contaminated by mercury. On top of that, there isn't a waste disposal system, so garbage lies everywhere. As a result, the average life expectancy of those living here is just 30-35 years!
