4. Earth’s Hell—Or Almost
Year Found: 1986
Est. Value: N/A
When scientists opened Romania’s Movile Cave in the twenty-first century, they discovered a self-contained biosphere after it had been closed for 5.5 million years. This remote underworld was found in 1986 and is home to 50 distinct species that have evolved to survive in the lethal hydrogen sulfide it emits. Chemosynthetic bacteria, which use carbon rather than oxygen as food, are the main players in the ecosystem.

Cave leeches, snails, scorpions, spiders, and other insects are among the occupants. Movile Cave offers a rare view into a prehistoric, self-sustaining ecosystem with possible significance for comprehending greenhouse gases.
