I understand this question to mean "local diversity of human culture" (and not, for example, local biological diversity).
Local diversity can mean for example different food - different areas have their own food specialties).
It can also mean the customs and religions - for example how people eat (fork, chopstics, hands, etc).
Another example is the clothing, for example in India many women wear Saris, while in Europe women wear skirts or trousers.
