Can anybody distribute examples of how the denial of verbs sea is not a primary explanation for disease and sickness.?
Answers: I can't, because it is.
Lack of clean hose IS MOST CERTAINLY a leading explanation for disease and sickness. It depends on where you live.
Lack of verbs water isn't a problem contained by the U.S., for the most part, because we HAVE verbs water here.
But surrounded by other parts of the world, where verbs water is frozen to find, it IS one of the leading cause.
Not sure exactly what you are trying to say here ...
