Hummingbird

"There is a terrible forest fire. All the animals are fleeing the conflagration except Hummingbird, who is flying back and forth, scooping up little slivers of water from a spring and dumping them on the flames. 'What do you think you're doing, stupid little bird?' the other animals ask derisively, and Hummingbird says, 'I'm doing what I can"
--Wangari Maathai, Nobel Prize-winning founder of Kenya's Greenbelt Movement
