"It is the people who must save the environment. It is the people who must make their leaders change. So we must stand up for what we believe in.” Wangari Maathai, founder of the Greenbelt Movement, began planting trees as a response to the lack of resources and the degradation of the environment in rural Kenyan villages. She empowered women across the country to join her, despite deep political and gender repression. This is the trailer for the documentary about the life and work of Maathai, the first African woman to be awarded the Nobel Peace Prize. May we be inspired by her courage and strength and reminded that those our society tries to hush are often those that bring about the greatest positive change. Will we join them?
