Dr. Wangari Maathai plants a forest.
(Book)

Wangari lives in the lush, green, land of rural Kenya where the soil is perfect for planting, the trees tower into the sky, and the streams are full of mysterious creatures. All day, she plays beneath her favorite fig tree, and at night she gathers around the fire with her family to listen to her mother's stories. Then Wangari grows up and goes away to school, and things start changing at home. Farmers chop down the trees. Landslides bury the stream. The soil becomes overworked and dry, and nothing will grow. People go hungry. After all her studies, Dr. Wangari Maathai realizes there is a simple solution to these problems: plant a forest full of trees. --from Amazon.
