Why is it said that culture is the mirror of civilization?

Culture is merely a reflection of civilization, a broad term given to describe mankind as a whole. Cultures are often influenced by the vernacular region's food, language, climate, and communal involvement. Although similar, I think that it is fair to say that culture serves as a microcosm for the big picture, which is our civilization as a whole. This may seem like an oversimplification, but the question purposed is too broad to answer with one, single response.
