September 11, by Saugat Adhikari In the course of human evolution, at a certain point in time, the idea of living in a group with mutual understanding and dependency became a very useful and practical lifestyle. From such small isolated groups, communities were formed. Then came the societies which in due time became a civilization. How the human mentality and psychology led to this huge change is still a popular topic among the historians and anthropologist, and a major discussion for another day.
Why Did the Mayan Civilization Collapse? A New Study Points to Deforestation and Climate Change A severe drought, exacerbated by widespread logging, appears to have triggered the mysterious Mayan demise smithsonian.
Why did the Maya, a remarkably sophisticated civilization made up of more than 19 million people, suddenly collapse sometime during the 8th or 9th centuries? Scholars and laypeople have proposed countless theories accounting for the collapse, ranging from the plausible overhunting, foreign invasion, peasant revolt to the absurd alien invasion, supernatural forces.
That hypothesis has finally been put to the test with archaeological evidence and environmental data and the results published this week in a pair of studies.
Interestingly, they also required massive amounts of wood to fuel the fires that cooked the lime plaster for their elaborate constructions—experts estimate it would have taken 20 trees to produce a single square meter of cityscape.
The central Yucatan lowland, site of most major Mayan cities, was abandoned due to the stresses of deforestation and drought. Using population records and measurements from current forested and cleared lands in the region, they constructed a computer model of deforestation in the Yucatan and ran simulations to see how this would have affected rainfall.
Because cleared land absorbs less solar radiation, less water evaporates from its surface, making clouds and rainfall more scarce. As a result, the rapid deforestation exacerbated an already severe drought—in the simulation, deforestation reduced precipitation by five to 15 percent and was responsible for 60 percent of the total drying that occurred over the course of a century as the Mayan civilization collapsed.
In a time of unprecedented population density, this combination of factors was likely catastrophic. Crops failed, especially because the droughts occurred disproportionately during the summer growing season.
Since the traditional elite relied largely upon this trade—along with annual crop surpluses—to build wealth, they were sapped of much of their power. The results are the ornate ruins that stretch across the peninsula today. Turnerthe lead author of the ASU study. In other words, the Maya were no fools.
They knew their environment and how to survive within it—and still they continued deforesting at a rapid pace, until the local environment was unable to sustain their society.
For a present-day example, we can even look to another region where the ancient Maya lived, Guatemala, which is undergoing rapid deforestation.Maya Culture & History - Archaeologists and linguists continue to unravel the ancient riddles of Maya Civilization, and we now have a better picture of .
Identification. The name Guatemala, meaning "land of forests," was derived from one of the Mayan dialects spoken by the indigenous people at the time of the Spanish conquest in For many people, the Zulu are the best-known African people.
Their military exploits led to the rise of a great kingdom that was feared for a long time over much of the African continent. What the hell are you talking about?!

AA culture produced the current POTUS. Black men spend more time with their children than white men. The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its hieroglyphic script—the only known fully developed writing system of the pre-Columbian Americas—as well as for its art, architecture, mathematics, calendar, and astronomical system.
The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and. Mayan Believes About the Milky Way and the Constellations. The Mayans had great reverence for the cosmos and the Milky Way. Traditionally it was believed in the Mayan culture that the Milky Way was the “Tree of Life”.
