Crash Course World History: The Role of Water in Civilization

Introduction

  • Hosted by John Green.
  • Focus on the rise and fall of civilizations through the lens of water resources.
  • Importance of resources and environmental issues due to Earth being our only planet.

Importance of Water

  • Water is essential for survival, agriculture, and raising animals.
  • Necessary for building cities, most places require irrigation.
  • Water management includes:
    • Dams and levees to control flooding.
    • Reservoirs, wells, and cisterns for water storage.

Water and Civilizations

  • Mayan Civilization (Central America):
    • Peak between 250 and 900 CE in Yucatan Peninsula.
    • Developed complex mathematics and writing systems.
    • Water management was crucial due to karst plain, poor soils, and low water table.
    • Water projects included ditches, reservoirs, cisterns, and canals.
    • Possible role of water in politics and religion; Holy Lords may have controlled water in exchange for tribute.
    • Collapse linked to droughts.

Khmer Civilization (Southeast Asia):

  • Flourished between 802 and 1327 CE in Cambodia.
  • Known for Angkor Wat and massive reservoirs.
  • Water issues different from Maya, but required significant labor.
  • Unclear functions of reservoirs: irrigation, flood control, or religious purposes?
  • Potential reasons for decline include environmental factors and weakened monsoons.

Environmental Impact

  • Water control remains a critical issue today.
  • Over a billion people lack access to safe drinking water.
  • By 2025, significant water shortages expected globally.
  • Lessons from history: be cautious of building large cities in arid areas.

Conclusion

  • Historical understanding helps guide present and future actions.
  • Acknowledgment of our interaction with the environment is crucial.
