Coastal societies are defined as the unity of collective social people living in coastal areas. Coastal societies are still very thick with their culture. As time goes by, the times are growing so that lead to the development of new cultures, including the new culture in coastal societies. The attitudes of the coastal societies towards the new culture are to accept the new culture, but the coastal societies also reject new cultures that are deemed incompatible with the culture that already exist in coastal societies. The social skills of coastal societies towards a new culture are to keep upholding existing cultural values.
