An American professor who studied the Mayans has come up with a new theory about the sudden end of their empire. According to Professor Richard Hansen , an archaeologist at the University of California , the collapse of the Mayan civilization in central American was brought about by the Mayans themselves .
Their object was to display their wealth and power by making their buildings and decoration as beautiful as possible. This involved using large quantities of lime , which they put on the walls to make them smooth. Unfortunately, the creation of lime is a process which requires intense heat, and they therefore had to cut down huge numbers of trees . This affected the quality of the soil , and it became almost impossible to farm.
Professor Hansen , who has just returned from an excavation in the El Mirador region of northern Guatemala , told a meeting of archaeologists in Philadelphia that the Mayas , having made this mistake in the 3rd century , repeated it 600 years later, at which time it proved fatal. Increasing food shortages among the Mayas created a Central American equivalent of the Peloponnesian War which ravaged ancient Greece . However, unlike the Greek civil war, which only lasted for 27 years , the Mayas wars went on for many centuries and left many of their great cities and temples ruins
