Which pre-Columbian civilization is often discussed in terms of possible decline due to drought and environmental stress?

• A. Mayan Civilization
• B. Inca Empire
• C. Aztec Empire
• D. Olmec Civilization

Answer: (A)

The idea being tested is how environmental stress, especially drought, can contribute to the decline of complex societies. The Maya are the most often discussed in this context because, in the Classic period, they built major cities in the lowlands that heavily relied on rainfall for maize agriculture and water systems. Climate evidence from tree rings, cave formations, and lake sediments shows prolonged droughts that align with periods of urban abandonment and agricultural strain in the southern lowlands. When rainfall failed for extended stretches, food supplies would waver, social tensions could rise, and political networks frayed, making drought a plausible contributing factor alongside other pressures. By contrast, the Inca, Aztec, and Olmec collapses are generally attributed more to factors like conquest, disease, or earlier cultural changes rather than drought-driven decline, so the Maya best fit the prompt about environmental stress playing a key role.
