Globalization, while fostering unprecedented intercultural exchange, simultaneously accelerates the erosion of linguistic diversity, posing an existential threat to marginalized indigenous languages through socio-economic hegemony and digital monolingualism. This phenomenon is not merely a byproduct of cultural assimilation but is structurally reinforced by institutional policies and market dynamics that privilege dominant lingua francas, thereby systematically marginalizing minority tongues in educational and administrative spheres. Although proponents argue that linguistic convergence facilitates global communication and economic integration, empirical studies consistently demonstrate that language loss correlates with irreversible declines in localized ecological knowledge and cognitive diversity, undermining long-term societal resilience. Consequently, sustainable language revitalization necessitates a paradigm shift from passive documentation to active policy intervention, integrating community-driven pedagogy, digital archiving innovations, and legislative recognition to reframe linguistic pluralism as a cornerstone of global intellectual heritage.
