The first African American woman to win the Nobel Peace Prize was Dr. Wangari Maathai, recognized in 2004 for her contributions to sustainable development, democracy, and peace. A Kenyan environmental activist, she founded the Green Belt Movement, which focused on tree planting, environmental conservation, and women's empowerment. Maathai's advocacy addressed environmental issues and social justice, highlighting the interconnectedness of environmental health and human rights. Her Nobel Prize win was significant as it elevated awareness of environmental concerns, particularly in Africa, and underscored the crucial role women play in sustainable development and peace-building efforts worldwide.
