Final answer:
Ecofeminism combines ecological concerns with feminism, challenging the patriarchal society's role in both gender inequality and environmental issues. Feminist ethics examines and seeks to correct the impacts of gender on moral beliefs and practices, and third-wave feminism has broadened these discussions with contemporary concerns.
Step-by-step explanation:
Ecofeminism is a movement that links feminism with ecology, arguing that patriarchal structures not only contribute to gender inequality but also to environmental degradation. It is considered an extension of feminism, which at its heart, is dedicated to achieving gender equality and challenging the historical dominance of the male perspective that has led to the marginalization of women's interests. Ecofeminism posits that this same patriarchal system is responsible for the exploitation of the natural environment, discerning a parallel between society's treatment of women and nature.
Feminist ethics, a branch of feminism, examines how gender roles and patriarchal systems impact moral beliefs and practices, aiming to eradicate sexism and advocate for social justice. It does not comprise a single coherent ethical theory but encompasses a diverse array of viewpoints and critiques which question historical biases that favor male perspectives.
Third-wave feminism, and potentially the emergence of a fourth-wave feminism, has expanded the scope of feminist ethics beyond traditional boundaries by condemning rigid gender binaries, advocating for fluid conceptions of gender, and endorsing sex positivity to advance women's sexual autonomy.
