Social justice movements significantly affect policy formation by raising awareness of inequality and injustices within society. These movements advocate for reforms that address issues like racial equality, environmental justice, and economic disparity. By mobilizing communities, engaging in protests, and utilizing social media, these movements create public pressure on lawmakers to prioritize legislative changes. Successful advocacy often leads to the introduction of new policies or the amendment of existing laws to enhance fairness and protect marginalized groups, thus reflecting the influence of grassroots efforts in shaping governance.
