The role of social media in contemporary global movements for change has been transformative. Platforms like Facebook, Twitter, and Instagram facilitate rapid information sharing and mobilization for causes such as Black Lives Matter and climate change activism. Social media enables grassroots organizing, allowing individuals to engage and collaborate across geographical boundaries. It amplifies voices that might be marginalized, fostering awareness and dialogue. Additionally, social media serves as a tool for accountability, allowing activists to document injustices. However, challenges like misinformation and online harassment also arise, complicating the landscape for activists.
