One of the most intriguing things about the Mayans was their ability to build civilizations in a tropical climate. They lived in the jungles of the Yucatan peninsula in today's Mexico.
The reasons that the Mayans lived in the jungles were because there they had what they needed in abundance. A few of these things were, obsidian (for tools), food, quetzal feathers which they turned into hats, and jade for decorations.
Spanish explorers did not like this area because there was no gold nor silver in the ground to be mined. The Maya build their buildings out of limestone, since it was in abundance. When the Maya went to war, they like to have trumpets made out of marine shells.
From late eighth through the end of the ninth century, A.D, the Maya disappeared from the jungles. Three theories for what happened are: 1. That the Mayans left because of the lack of resources in the jungle, 2. Died fighting each other 3. There was a catastrophic drought and the Mayans had no food and had to leave.
