Oxygen producing ocean plants are intentionally killed in a clandestine effort to repopulate the planet with mutated humans. A group of scientists try to halt the destruction. It reads better then it sounds.
I first read this book almost 20 years ago, and every time I think about it, I get the chills. So many of the issues Mr. Hoyle addressed (even though fictionalised) have come to pass. I have seen in my life time the world change -- climate wise, geographically, etc. This book made me aware of the environment, and brought home to me just how destructive and selfish mankind can be in its blind pursuit of progress and exploitation of natural resources. Any one who reads this will go to bed every night with a sinking feeling in the pit of their stomach. Why? Because the fiction in the book is becoming fact in our lifetime today... amazon review
