The mysterious decline of the Mayan Civilization has had several great scientists scratching their heads, and drawing several conclusions regarding the decline. Until now: the Blue Hole of Belize seems to hold a promising solution to this problem.A research team consisting of scientists from Rice University and the Louisiana State University collected samples from the Great Blue Hole and nearby lagoons, comparing the concentration of titanium and aluminum within them; higher titanium concentrations indicate heavy rainfall. The team found a major shift from titanium to aluminum content from the ninth to the tenth century. From A.D. 800 to 1000, the ratio between the two elements decreased even further, indicating a decrease in the amount of rainfall in the region, thus supporting prevailing beliefs that droughts and similar, unsuitable climatic conditions led to the downfall of the Maya. The research also hinted at a possible second drought hitting the region between 1000 and 1100 A.D.The Mayans relied heavily on rainfall, as the regions they inhabited, such as the Yucatan Peninsula, severely lacked natural water resources. Lesser rainfall with the years seems to be a plausible reason for the Mayans becoming a lost civilization.
This research comes in the wake of others that claim that the fall of the Mayan civilization is a result of climate change: in 2012, scientists collected stalagmite samples from a cave in Belize, and achieved results that pointed to droughts as being the central cause for the Mayan decline.
This research could, hopefully, settle the problem of the Mayan Civilization once and for all.
