furious milk

Was discussing the not-very-well-explained subplot of "mother's milk" in Mad Max: Fury Road with a family member recently.
Yes, what was that all about?
A quick surf around the non-Facebook internet yielded some info:

This site explains the role of breast milk in the film's future barter economy. I guess we could say the movie shows us all this rather than tells it (hey, there's action we have to do here).

A geek wonders if there was a deleted scene explaining the mother's milk.

Another writer develops an elaborate web of ecofeminist theory based on the film's few hints of botched exposition. What the heck -- go for it.

So there you have it.
