John Ronald Reuel Tolkien CBE FRSL was an English novelist, poet, philologist, and scholar best known for his high fantasy works The Hobbit and The Lord of the Rings.

Since the 1970s, critics have remarked on the subject of environmentalism in The Lord of the Rings. The Hobbits' visions of Saruman's industrial hell of Isengard and Sauron's bleak polluted land of Mordor have been translated as critiques of contemporary civilization. In contrast, the tree-giant Ents' ruin of Isengard and the Hobbits' "The Scouring of the Shire" have a clear theme of natural habitat regeneration after such industrial waste and deterioration. On the other hand, Tolkien's love of trees and unspoiled nature is evident in the book.
