Interactions between group members
- interactions with people outside of the group
- interactions with the environment
Explanation:
The culture is the most powerful tool of any society. It is unique to each group, and it is what defines that group of people. The culture has the ability to shape up three types of interactions:
- interactions between group members
- interactions with people outside of the group
- interactions with the environment
The interactions between the group members are good in general, as they belong to the same culture and have lot of similarities. An example can be the interaction between two neighbors.
The interaction with people outside of the group can go either way though. If there are some similarities between the cultures then the people will most probably become close, but if there are big differences, it will most probably cause conflict. An example can be the interaction between a Catholic Mexican and Muslim Arab.
The interaction with the environment is crucial for any culture, and every culture has special and different interaction with it, depending on its characteristics. An example of this can be that the Celtic people considered the trees to sacred, and some trees such as the willow for forbidden for cutting as it was of highest rank.
