With my contribution, I aim to explore, in the light of a theoretical approach, several examples of ecofeminism, that is, the union of feminist emancipation efforts with those that seek to safeguard the endangered terrestrial ecosystem. I will first begin with a brief introductory note on the environmental sustainability issue, a dominant topic in today's society, followed by a theoretical exploration of the key concepts of this study—ecofeminism, based on the work of scholars like Tickner, J. and Sjoberg, L. (2016) and Evans, J. (1993). Next, I'll examine how and to what extent these theoretical concepts are applied to reality through the analysis of three ecofeminist movements—Dr. Shiva and the Indian ‘Navdanya’ movement; the Green Belt Movement in Kenya and Germany’s Green Party case—whose actions merge the feminist reality with the environmentalist, seeking to achieve both gender equality and the sustainability and protection of planet earth. In the final part, I will explore the various criticisms that ecofeminist theory and movements face, stemming from some of their theoretical and practical perspectives, and then reflect on whether ecofeminism is, in fact, a useful tool in the fight for women's rights and the survival of our planet’s ecosystem as we need it.
