During the peak of their civilization, the population grew rapidly, which demands more food sources. However, the agriculture is not able to support sufficient food because of bad soil condition. The long-term series of drought hindered a century-scale decline in rainfall, in which restrains the Mayan on resources in the region, and contributed to social issues (warfare) that led to the demise of Maya civilization. With limited resources, the Mayan therefore burned and cut more and more forests in searching for a better land to farm. Nevertheless, due to the high temperature and reduction of rainfall, the lands were dried up, making it less suitable for farming. Tom Sever, NASA’s only archaeologist, has been exanimating Mayan ruins using satellites.
