Make Room! Make Room!

Blurb

Make Room! Make Room! is a 1966 science fiction novel written by Harry Harrison exploring the consequences of unchecked population growth on society. It was originally serialized in Impulse magazine.
Set in then-future August 1999, the novel explores trends in the proportion of world resources used by the United States and other countries compared to population growth, depicting a world where the global population is seven billion, subject to overcrowding, resource shortages, and a crumbling infrastructure. The plot jumps from character to character, recounting the lives of people in various walks of life in New York City.
The novel was the basis of the 1973 science fiction movie Soylent Green, although the movie changed much of the plot and theme and introduced cannibalism as a solution to feeding people.
