Explanation: Anthropology is the holistic scientific and social study of humanity, mainly using ethnography (culture and society) as its method. Public anthropology addresses broad questions about what it means to be human in modern day societies and cultures, as well as those of the recent past while opposing policies that violates the rights of persons and unfairness to parties. It largely demonstrates the ability of anthropology to effectively address problems beyond the discipline—illuminating larger social issues, human rights etc. of our times as well as encouraging broad, public conversations about them with the ultimate goal of fostering social/societal change.
