Name a major environmental factor that contributed to the decline of classical civilizations.

• A. Volcanic eruption
• B. Drought and environmental stress
• C. Heavy rainfall leading to floods
• D. Earthquakes

Answer: (B)

Environmental stress from climate variability directly tests a civilization’s ability to feed its people and maintain stability. When droughts hit, harvests fail, food becomes scarce, prices rise, and tax and tribute systems falter. This weakens state institutions, strains resources for defense, and can push populations to migrate or rebel. Across different regions, prolonged drought and environmental stress coincide with periods of decline or upheaval in classical civilizations, such as the Maya and other polities that faced farming shortfalls and social disruption. While volcanic eruptions, heavy but isolated floods, or earthquakes can cause damage, they are typically episodic or localized and don’t usually drive long-term, widespread decline the way sustained environmental pressure does.
