The Baldwin Entertainment Group have bought the rights to Julia Butterfly Hill's book
The Legacy of Luna, according to the Hollywood Reporter.
The true-life story centers on Hill's two-year stint living in a tree she called Luna in an attempt to thwart the Pacific Lumber's plans to destroy a forest of California redwoods.
In December 1997, Hill climbed the tree and refused to come down, hoping to bring attention to her cause and save the forest. She came down 738 days later after reaching an agreement that provided permanent protection for the tree and a buffer zone around it.
