The earth is in crisis from overpopulation but people don’t seem to care. Too many deny it. This book debunks arguments and lays out the facts. It is not a pleasant read. Much of it is not new, or is self-evident. Some of it is technical. But it makes its case well. The population problem is all-encompassing in its effects and this book is comprehensive in its coverage. Have you heard about the garbage crisis?

Published in 1991, this book is not always up to date, but its premise is valid and more relevant than ever. Things have only gotten worse—the planet has added a billion and a half more people since then. Have the authors’ predictions come true? They are in progress.

The population explosion was “the most important, astounding, and far-reaching event of the twentieth century,” say the Ehrlichs. It threatens the very habitability of the planet. Why has there been so little discussion of it? They call for a mass movement to forestall global catastrophe, and discuss in detail what needs to be done.

Highly recommended to anyone who still thinks that population is not a problem. ( )
