"Julia Butterfly Hill (born 18 February 1974) is an American activist and environmentalist. Hill is best known for living in a 180-foot-tall, 600-year-old California Redwood tree for 738 days between 10 December 1997 and 18 December 1999. Hill lived barefoot in the tree, named "Luna", to prevent loggers of the Pacific Lumber Company from cutting it down. Hill lived in a small 6-by-8-foot shelter that she had built with help of other volunteers.

A native of Jonesboro, Arkansas, Hill suffered a mild brain injury in a car crash a year before her tree-sitting experience.[1] She embarked on a spiritual quest afterwards, rejected the faith of her childhood and came away believing that we could transform ourselves; this eventually lead her to the environmental cause opposed to the destruction of the redwood forest in Humboldt County, California. Originally, Hill was not officially affiliated with any environmental organization, deciding upon herself to undertake the act of civil disobedience. Soon, Hill was actively supported by Earth First!, among other organizations and volunteers." Wikipedia
