Social change comes from close relationships and the mutual friends that come with that. In the movie, “Do the Math”, featuring Bill McKibben, he discusses what needs to happen in order for climate change to be suppressed and for things to change socially and economically on a global scale. McKibben states, “If you are a member of a church, you have the ability to work with your fellow congregates to make sure that your church is not investing in fossil fuel companies” (11). He’s saying that ideas can radiate to other people if you’re involved in small groups/organizations because then those close ties you have can spread that idea to their ties and the word gets further and further. Another author that discusses social change discusses how this social change can really be pushed to occur with mutual and close friends interwoven together. Duhigg states, “Strong ties, or close relationships, combined with weak ties, or distant connections, have the power to mobilize large groups toward a singular goal” (85). Duhigg is saying that these connections that cross societal boundaries are what can really push a political and social change to occur. Just like what McKibben said with climate change and the church groups, they can have lots of power and political force because of the different people they can reach. Duhigg ties this up by stating that these strong and weak ties are the driving force in political change.
