Social movements are catalysts for change in public policies by mobilizing grassroots support, raising awareness, and advocating for specific issues. They challenge the status quo and bring attention to marginalized communities' needs, ultimately influencing public opinion and legislative agendas. Successful movements often leverage media strategies, coalition-building, and direct action to hold policymakers accountable and push for reforms. The resulting shifts in policy can significantly affect social justice, human rights, and environmental sustainability, reflecting the power of collective action in shaping governmental priorities.
