The document discusses different forms of social media activism, including "slacktivism" where people show support for causes with minimal effort. It provides examples like hashtags and "likes" that allow activism with just a click but may not create real change.

The #BringBackOurGirls campaign around the kidnapping of Nigerian girls in 2014 showed how a hashtag can spread awareness globally and help apply pressure through online petitions and rallies to address an issue.
