Social justice movements challenge systemic injustices by mobilizing communities to address issues such as inequality, discrimination, and oppression. These movements utilize various strategies, including advocacy, awareness campaigns, and direct action, to expose injustices and demand changes in policy and societal norms. By amplifying marginalized voices and highlighting their struggles, social justice movements push for policies that promote equity and inclusion. Their impact can lead to significant legal reforms and shifts in public consciousness, ultimately fostering a more just and fair society.
