About the book: 1981 / The Earth is inhabited by 50 billion people. All natural resources have been exhausted. KK go in search of worlds suitable for settlement. One of them is Altair VI. The planet is covered with a toxic atmosphere through which sunlight never penetrates. It is inhabited by wolves - three-ton, six-legged predators with vision in the infrared range, as well as monkey-like creatures and other animals. People catch them, insert probes into their brains, and then force them to build a station to transform the atmosphere.
