Earth in the Balance audio book cover
Earth in the Balance: Ecology and the Human Spirit (ISBN 0-452-26935-0, paperback ISBN 1-85383-743-1) is a 1992 book written by Al Gore, published in June 1992, shortly before he was elected Vice President in the 1992 presidential election. Known by the short title Earth in the Balance, the book explains the world's ecological predicament and describes a range of policies to deal with the most pressing problems. It includes a proposed "Global Marshall Plan" to address current ecological issues.
Written while his son was recovering from a serious accident, Earth in the Balance became the first book written by a sitting U.S. Senator to make the New York Times bestseller list since John F. Kennedy's Profiles in Courage. 
In 1993, Earth in the Balance was released in paperback and audio-book format on audio cassette tape.
The book was followed by An Inconvenient Truth, a book that was the companion for a movie narrated by Al Gore, shown at the 2006 Sundance Film Festival and released on 24 May, 2006.
In the Futurama episode "Crimes of the Hot," Al Gore himself references the book and its "far more popular" fictional future sequel, Harry Potter and the Balance of Earth.
