Ethnobiology
Ethnobiology is the scientific study of the way living things are treated or used by different human cultures. It studies the dynamic relationships between peoples, biota, and environments, from the distant past to the immediate present.
"People-biota-environment" interactions around the world are documented and studied through time, across cultures, and across disciplines in a search for valid, reliable answers to two 'defining' questions: "How and in what ways do human societies use nature, and how and in what ways do human societies view nature?"
