Anti-globalization movements challenge mainstream politics by critiquing the effects of globalization on national sovereignty, labor rights, and environmental policies. These movements argue that unchecked global economic policies often prioritize profit over people, leading to inequality and cultural homogenization. They advocate for more localized, sustainable approaches to economic and social issues, emphasizing the importance of retaining local power in the face of global pressures. By mobilizing grassroots support, these movements aim to reshape public discourse around trade agreements, corporate influence, and economic justice, thus holding mainstream political entities accountable for their actions.
