The research analyzed women's mobilizations in 2019 -- the first year of the current ultraconservative government in Brazil -- focusing on the peasant women and indigenous women's demonstrations. The text points that the further liberalization and deregulation of environmental protection coupled with anti-indigenous and anti-environmentalist rhetoric leads to the intensification of extractivism (agribusiness, mining, among others), which advances on communities' lands, water, soil and forests. Because they are directly impacted by the social and environmental damages, women became the main social force fighting against the commercialization of nature and also supporting the subsistence-oriented agriculture. Considering the current environmental collapse, it's argued that those struggles are urgent for the defense of life and, therefore, should be supported by critical environmental educators.
