Presenter: Today I'd like to share with you how social media is being used, not only to help students connect, but also as a powerful tool to advance social causes and motivate us to act on their behalf. We'll start by looking at a compelling theory of why social media is so uniquely suited to forging these connections. Next, I'll review some data on social media's meteoric rise. Finally, we'll see how today's activists are harnessing social media to support an array of social causes to make life better for us all.
