What are the motifs in Bowling Alone by Robert D. Putnam?

In many ways, Bowling Alone is about the social connections that people have with each other. Putnam argues that these connections have been declining in recent years, as Americans become more isolated and individually orientated. He believes that this has led to worse health, more depression, more suicide, more unhappiness, and less trust in others. The decrease in social connections has also led to a decrease in social capital, which has had negative effects on communities and families as well.
