Green Rage: Radical environmentalism and the unmaking of civilization (1990, Boston, MA.)
One of the first books I bought about radical wilderness defense was Green Rage. It is an excellent investigation of the origins of (western) environmental radicalism, and I recommend that you read it cover to cover.
Speaking of covers, you might notice that this particular copy of Green Rage is a little ragged. The reason for that is because this is my copy, and after reading the book I took it’s message to heart. Several years ago in Oregon, a small group of activists from around the region were protesting at a breeding facility that supplied rabbits to the vivisection industry. When we arrived the farms owners were not present, and neither were any law enforcement. Not coincidentally I quickly found myself living with some critters who liked to chew on everything in our humble home. I hope you will enjoy Green Rage as much as they did!
