Through this review paper, the authors aim to examine global development policies under which-despite the significant contribution of resources from the Third World Countries to the development process- these countries are not only deprived of its fruits but are also compelled to bear the brunt of the resulting climate and environmental crises. Drawing upon secondary literature, the authors have also endeavoured to analyse the process of the thirdworldization of environmental crises, while simultaneously delineating the limitations of newly emerging, mining-centric globalization policies- policies that have given rise to countless instances of discontent and social movements across various countries of the Third World. An effort has been made to cite examples of this discontent wherever possible in order to demonstrate how the environmental crisis is inextricably intertwined with socio-economic crises. To frame this discourse, three countries from the Third World have been selected, namely- Nigeria, Mexico, and Bangladesh- representing Africa, Latin America, and Asia respectively, all of which stand as major victims of climate injustices. Given the inherent limitations in accessing comprehensive research literature on the aforementioned subject, citing contemporary references at various points throughout this paper may, at times prove challenging.
