principles of multicausality

The logical course of action when given a problem to solve is to first find the cause of the problem.  In human services, multicausality complicates this process.  Discuss the core principles of multicausality, and explain how this concept is central to understanding the human service field.  Provide an example of how ignoring multicausality might lead to an inadequate strategy of intervention when attempting to manage a specific problem.  For example:  Prohibition was implemented to curb drinking without an understanding of the complexity of alcohol abuse.  Include at least three of the principles of multicausality in your example to highlight your understanding of this concept.
