In the mid-1970s, this Kenyan woman organized the Green Belt Movement that organizes women in rural Kenya to plant trees, combat deforestation, restore their main source of fuel for cooking, generate income, and stop soil erosion. Since she started the movement, over 40 million trees have been planted. Over 30,000 women have been trained in forestry, food processing, bee-keeping, and other trades that help them earn income while preserving their lands and resources. Communities in Kenya (both men and women) have been motivated and organized to both prevent further environmental destruction and restore that which has been damaged. In 2004, she received the Nobel Peace Prize.
