Anthropologist ralph linton said, "the last thing a fish would ever notice would be water." what does this imply about culture

''The last thing a fish would ever notice would be water'' is a statement that can easily be connected with the humans societies and their culture. With this statement, Linton practically says that the humans, if put on the place of the fish, would notice the last the things that they experience everyday, and which are crucial for their survival, such as the water, food, and air. This implies that the humans would only notice that their environment and basic things for living only when there will large scale problems with it.
