Environmental anthropology is a branch of anthropology that examines the complex and dynamic relationships between human beings, cultures, societies, and their physical and biological environments. It studies how people understand, use, modify, manage, and adapt to their environments and, at the same time, how environmental conditions influence human life, social organization, cultural practices, economy, health, and belief systems. The field recognizes that the environment is not merely a physical background to human society but is closely connected with human activities, cultural meanings, political institutions, and economic systems. Environmental anthropology therefore provides an integrated understanding of environmental issues by combining anthropological perspectives with insights from ecology, geography, biology, economics, political science, and other disciplines. The central concern of environmental anthropology is the relationship between culture and environment. Different societies interact with similar environments in different ways because their knowledge, technologies, values, institutions, and economic systems differ. For example, communities dependent on forests may develop detailed knowledge of plants, animals, soils, and seasonal changes. Such knowledge may influence their food habits, medicine, religious practices, settlement patterns, and resource-management systems. Environmental anthropology seeks to understand these relationships and examines both traditional forms of environmental adaptation and the consequences of modern economic and technological change. The roots of environmental anthropology can be traced to the development of anthropology during the nineteenth century. Early anthropologists were interested in explaining differences between human societies and their relationships with geographical and environmental conditions. However, some early approaches were strongly influenced by environmental determinism, which argued that climate, geography, and other physical factors largely determined human culture and social development. Such explanations often reduced complex cultural processes to environmental conditions and sometimes supported evolutionary ideas about the supposed superiority of particular societies. During the late nineteenth and early twentieth centuries, anthropologists increasingly rejected simplistic environmental determinism. Franz Boas played an important role in emphasizing historical particularism and cultural diversity. He demonstrated that human cultural practices could not be explained simply through environmental conditions. Culture developed through historical experiences, social processes, migration, and interaction. Nevertheless, environmental factors remained important in understanding how societies adapted to particular surroundings. A major development occurred in the first half of the twentieth century with the emergence of ecological approaches in anthropology. Julian Steward was particularly influential in developing the concept of cultural ecology. Steward argued that certain aspects of culture are closely related to the ways in which people adapt to their environments. He focused especially on subsistence activities, technology, and patterns of social organization. His approach did not claim that the environment mechanically determines culture. Instead, it examined the interaction between environmental conditions, technology, and cultural practices. Steward's cultural ecology became an important
