Human Ecology

Human ecology is the interdisciplinary study of the relationships between human populations and their environments, encompassing natural, social, and built surroundings. As a branch of human biology, it investigates how humans adapt to and actively shape their ecosystems, examining the complex, two-way interactions between social organization, culture, and technology on one side, and the physical and biological world on the other. This field analyzes everything from the impact of urbanization on local climates and biodiversity to the ways in which resource availability influences human settlement patterns, health, and cultural development, ultimately seeking to understand the conditions for sustainable human-environment systems.
