LIFE IN THE RAINFOREST
One of the many intriguing things about the Maya was their ability to build a great civilization in a tropical rainforest climate. Traditionally, ancient peoples had flourished in drier climates, where the centralized management of water resources (through irrigation and other techniques) formed the basis of society. (This was the case for the Teotihuacan of highland Mexico, contemporaries of the Classic Maya.) In the southern Maya lowlands, however, there were few navigable rivers for trade and transport, as well as no obvious need for an irrigation system.
By the late 20th century, researchers had concluded that the climate of the lowlands was in fact quite environmentally diverse. Though foreign invaders were disappointed by the region’s relative lack of silver and gold, the Maya took advantage of the area’s many natural resources, including limestone (for construction), the volcanic rock obsidian (for tools and weapons) and salt. The environment also held other treasures for the Maya, including jade, quetzal feathers (used to decorate the elaborate costumes of Maya nobility) and marine shells, which were used as trumpets in ceremonies and warfare.
