Environmentalism with an altitude
A 1,000-year-old redwood tree named Luna was home to activist Julia Butterfly Hill for 738 days, 1997 through 1999. Hill lived in the tree for two years to protest the Pacific Lumber Company's plans to cut down a section of northern California's famous redwood forests. While 180 feet in the air in Luna, Hill founded the Circle of Life Foundation to work for solutions to environmental and social problems. After descending Luna, Hill began traveling around the country to speak to schoolchildren, college students, labor unions and others.
