What i'm really confused. Is this just for points?
Answer:
Hostile Indians, starvation, poor leadership, lack of government, cannibalism, lack of skills among colonists.
Well, it depends on how you write. As you may know,a external conflict is a conflict occurring outside, like tornado or fires. A internal conflict is a conflict occurring inside like emotions. You could write about a man surviving on a island, balancing the external conflict (weather, hunger, etc) while still maintaining the emotional conflicts (misses family, difficult to kill animals).
