In July 1987, Abbey went to the Earth First! Rendezvous at the North Rim of the Grand Canyon. While there, he was involved in a heated debate with an anarchist communist group known as Alien Nation, over his stated view that America should be closed to all immigration. Abbey devoted an entire chapter in his book "Hayduke Lives!" to the events that took place at the Rendezvous. In autumn of 1987, the "Utne Reader" published a letter by Murray Bookchin which claimed that Abbey, Garrett Hardin, and the members of Earth First! were racists and eco-terrorists. Regarding the accusation of "eco-terrorism", Abbey responded that the tactics he supported were trying to defend against the terrorism he felt was committed by government and industry against living beings and the environment.
