Her founding of the Green Belt Movement empowered women to participate in tree planting, fostering both environmental stewardship and economic independence. Maathai's focus on the interconnectedness of environmental and social issues emphasized the need for a holistic approach to development, inspiring countless activists globally to address both ecological and social justice.
