Understanding the Polder System

The video explores the necessity for specific environments for human habitation and the increasing demand for living space due to population growth. It introduces the polder system, a method of land reclamation from the sea, primarily used in the Netherlands. The process involves using dikes to contain water and pumping it out to create usable land. The history of the polder system dates back to the 12th century in the Netherlands, where it was developed to combat flooding and create agricultural land. Today, polders are found in several countries, including South Korea, Germany, India, and Canada. The polder system has been instrumental in providing solutions to land scarcity and has significantly impacted human adaptation to environmental challenges.
