The Maya civilization was one of the most advanced of its time, sporting cities and populations that rose to the millions. Yet during the 8th or 9th centuries, a sudden collapse spelled the end of this vast civilization. Now, scientists are taking a closer look at what might have led to this catastrophic collapse.
Researchers actually took minerals from Belize's famous underwater cave, known as the Blue Hole, along as lagoons nearby. These minerals showed that an extreme drought occurred between AD 800 and AD 900, which is right when the Mayan civilization collapsed, according to LiveScience.
