Wangaari Maathai grew up on a farm in Kenya. When she left Kenya to attend college in America, she took with her memories of a country clothed in green, with many trees and clear streams filled with fish. Although she was only away for five years, she returned to a very different Kenya. Many of the trees had been cut down and replaced with farms to grow export crops; in places the land was barren. Small farms that had provided food for each family to live on now grew food to export and families bought most of their food from the store. The effects of erosion were evident in the muddied streams.

There are many ways in which Wangaari could have responded to the changes in her native country. The inspiring story of the path she chose is told in the book, Planting the Trees of Kenya, by Claire A. Nivola.
