Julia Butterfly Hill, American environmentalist and author

Julia Lorraine Hill, best known as Julia Butterfly Hill, is an American environmental activist and tax redirection advocate. She lived in a 200-foot (61 m)-tall, approximately 1,000-year-old California redwood tree for 738 days between December 10, 1997, and December 18, 1999. Hill lived in a tent near the top of a tree, affectionately known as Luna, to prevent Pacific Lumber Company loggers from cutting it down. She ultimately reached an agreement with the lumber company to save the tree. Hill is the author of the book The Legacy of Luna (2000) and co-author of One Makes the Difference.
