The Life and Death of Planet Earth (full title: The Life and Death of Planet Earth: How the New Science of Astrobiology Charts the Ultimate Fate of Our World) is a popular science book by paleontologist Peter Ward and astronomer Donald E. Brownlee.

The book discusses Earth's future and eventual demise as it is ultimately destroyed by a warming and expanding Sun.

The Earth's lifespan is compared to that of a living being, pointing out that the systems which keep it habitable will gradually break down one by one, like the organs in an aging human body.

[1] Fraser Cain called the book depressing on Universe Today, but said that the authors "tell an engaging story" and that the scientific terminology used is well explained.

[3] The verdict of Kirkus Reviews was "Far from cheerful, but fascinating", while pointing out that the authors tended to move quickly from fact to their own personal theories, and that the prose was not of the highest standard.
