The Nitrogen Fix - Hal Clement


This copy of The Nitrogen Fix by Hal Clement is a first mass market edition paperback, published by ACE Science Fiction in 1981. The book is slightly beat up with some cover damage, and the spine is rolled. The book is still in good condition.

From Goodreads:
"2000 years from now, the Earth has acid oceans, mutating exploding plants, silent, tentacled observers, doomed Hill cities, nomad Outcasts, vicious, power-mad rebels. The Earth does not have oxygen; it has all been trapped in The Nitrogen Fix, a novel of the ultimate ecological disaster."
