Ellsworth Huntington was an American geographer and climatologist born in 1876. He is best known for his work on the relationship between climate and human behavior, particularly how environmental factors influence the development of civilizations. Huntington's theories suggested that climate could shape cultural and social progress. Huntington's most notable work, "Civilization and Climate," published in 1915, argued that temperate climates fostered more advanced societies compared to tropical regions. His ideas sparked significant debate and contributed to the fields of geography and environmental science, although some of his conclusions have been criticized for oversimplification and determinism.
