You must approach it from a sociological viewpoint. This means taking into account how the issue is embedded within a social structural, cultural and institutional context. In general, a good rule is to ask yourself: “How does what I’m studying intersect with other social structures/institutions, and how might those structures/institutions be reformed or adapted to better deal with the issue and/or improve the outcomes for those affected by it?”
