Wangari Maathai grew up in the Kenyan highlands. Fig trees covered the hills, fish were abundant in the streams, and people tended their own gardens. After attending college in the U.S., Wangari returns to a changed Kenya. The trees are gone, the people are malnourished, and the village gardens are dry. In 1977, Wanagri begins the Green Belt Movement, where individuals learn to care for the environment. She received the Nobel Peace Prize in 2004.
