Global justice theories examine inequality, poverty, and human rights on a global scale. Thinkers like Fanon, Sen, and Pogge have shaped this field by critiquing colonialism, emphasizing individual capabilities, and highlighting structural injustices in the global economic order. These approaches challenge traditional views of justice, emphasizing the need for a global perspective. They've influenced debates on issues like poverty, climate change, and development, providing frameworks for evaluating global institutions and policies. Their ideas continue to shape contemporary discussions on global challenges.
