I'm so sorry I didn't see this question before. Yes, it does. Sometimes it's also used to imply hazardous beach conditions.
I believe it's more about the power of the ocean and how dangerous it can be if you underestimate it than a statement about how we cannot survive without it.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
