Many years ago I read a book called The Bridge by D. Keith Mano. It was an extraordinary story and changed forever the way I thought about environmentalism.
The book was first published in the early 1970's and it's taken this long for me to find a copy. The used paperbook cost me $1.95 and the shipping was $4. Cheap for a monumental bit of prophecy.
Here's the back-cover blurb: "The time is the near future. Humanity has lost its will to live. Everywhere primeval nature is reclaiming the Earth from the species that has for so long dominated it. The government itself has abandoned the struggle and has even decreed the suicide of civilization."
The author is listed in IMDB but I cannot find any contact info for him. If you can track him down, or if you know him, please get in touch with me.
This story, long out of print, deserves to be available online and I'd be happy to host it.
UPDATE: Professional researcher Catherine Lucy tracked him down to his family's company. I'll start with the phone calls next week. Thanks, Catherine.
