It started with seven trees planted for people who were already dead
Wangari Maathai's first environmental act was a memorial march through Nairobi. Fifty-one million trees later, it earned a Nobel.
On June 5, 1977, a small group of women marched from the Kenyatta International Conference Centre in downtown Nairobi to a park on the city's outskirts and planted seven trees, one for each of several historical community leaders they wanted to honor. Nothing about the gesture announced itself as the start of a movement. It read as a memorial, small and local, over in an afternoon.
Wangari Maathai, the biologist who organized it, kept going. She recruited rural women to gather seeds from nearby forests, grow tree nurseries, and plant seedlings on degraded land, paying each woman a small stipend per tree. The pitch wasn't abstract environmentalism; it was firewood, fertile soil, and income, delivered through work women could do without waiting for permission from anyone above them.
That effort became the Green Belt Movement. Over the following decades it trained more than 30,000 women in forestry, beekeeping, and food processing, and planted more than 51 million trees across Kenya. In 2004, Maathai became the first African woman to win the Nobel Peace Prize, awarded specifically for connecting environmental restoration to democracy and peace.
The seven trees weren't a symbolic launch of a plan already sketched out. They were the whole plan, at the only scale available that day, repeated until the scale changed on its own.
