Mike Roselle’s stunts as an environmental activist aren’t for the weak-kneed. He’s stood the line in front of charging bulldozers to fight against the logging of old-growth forests, organized protests against acid rain, blockaded ports to shut down illegal mahogany trade and practiced several other forms of what he calls “creative confrontation.” Not surprisingly, Roselle’s been arrested in nonviolent protest many, many times. The cofounder of San Francisco-based Rainforest Action Network, Earth First!, and The Ruckus Society, Roselle has dedicated his life to environmental causes. Despite taking part in protests that have turned violent and witnessing a new breed of eco-terrorism, Roselle doesn’t support violence. Ultimately, he presents a compelling case for activism rooted in the tradition of nonviolent civil disobedience. His memoir, Tree Spiker, is a call to action as much as it’s an inspiring account of this man’s struggle to save the planet, one tree at a time.
