A Plague of Frogs : The Horrifying True Story Review

Average Reviews:

(More customer reviews)Mr. Souder has the rare ability to bring abstruse science to life without bias or over-simplification. He is also a keen observer of the human species and its political interactions.
This is indeed "the horrifying true story," one I wish would go away; yet the author's presentation is dispassionate, thorough, and as non-alarmist as possible for a subject this spooky.
The book offers a good overview of current environmental science research in addition to its difficult detective story: what's responsible for these massive levels of gross deformities in frogs?
