A 20th Century Dilemma

The planet Earth is a spaceship-a small, self-contained system with limited resources-and the Earth's people are passengers on that spaceship.

What would happen if the provisions ran low? The water supply became polluted? Mutinies and fighting started to break out? The energy supply was being depleted?

You had better start thinking about what you would do because you are on that spaceship!

Isaac Asimov probes vitally important questions about our population problems and what we must start to do to bring about solutions.
