Journalist Mark Hertsgaard interviews 2004 Nobel Peace Prize laureate Dr. Wangari Maathai. The Honorable Professor Maathai is the first woman, the first Kenyan and the first environmentalist to win the prize. She was selected for her role in founding the Green Belt Movement, which for nearly 30 years has sought to empower women, improve the environment and fight corruption in Africa. She also won acclaim for her campaign to fight deforestation by planting 30 million trees in Africa, making her Nobel Peace Prize the first to acknowledge environmentalism as a means of building peace through pre-empting conflict over increasingly scarce resources. She is Kenyan by nationality, a biologist by training, an activist by occupation and now a member of the government in Kenya as Minister for the Environment and Natural Resources.
