Wangari Maathai was a Kenyan environmental hero who taught that a single seed could save forests and change history. She was born in 1940 in the village of Ihithe, Nyeri, where she grew up playing under giant fig trees,  trees she believed were sacred. After studying biology in the United States and becoming the first woman in East Africa to earn a PhD, she returned to Kenya and was shocked by the pace of environmental destruction.

In 1977, she founded the Green Belt Movement. Wangari saw that deforestation was causing rivers to dry up and rural hunger to rise. She started with a few women, teaching them to plant native trees such as Muringa (Moringa), Mukuyu (Sycamore Fig), and Mvule (African Teak / Iroko). Unlike exotic trees, these native trees protected the soil and water sources. Wangari traveled through villages giving practical advice: "Dig a hole twice the size of the roots, water it every day, and protect the tree from goats." For each tree that survived, the women received a small payment, which gave them economic power and respect in their communities.

Wangari's activism was not just about the environment, but also about social justice. In 1989, she led the fight against a government plan to build a 60-story building in the middle of Uhuru Park, the lungs of Nairobi. Despite being beaten and arrested by the police, her steadfast stance led to the investors withdrawing and the park being left for the public. in 1999, she also saved the Kurura Forest from land grabbing. She faced bulldozers with a sapling in her hand, insisting that the environment cannot be sold for the profit of a few.

By 2004, the Green Belt Movement had planted an estimated 30 million trees. That same year, Wangari Maathai made history by becoming the first African woman to be awarded the Nobel Peace Prize. The Nobel Committee recognized her contribution to linking environmentalism, democracy, and peace. She said: "Trees are a symbol of peace; when we fight over scarce resources, peace disappears." Wangari died in 2011, but her legacy lives on. Today, Kenya has set ambitious goals to plant billions of trees, a continuation of the dream of this Nyeri woman who believed that change comes with a single seed.
