The third edition of Hardin’s well known General Biology text can be summarized by two words—bigger and better. But perhaps the more important comment is that Hardin’s books are not just about Biology; he writes as a person of the world, concerned about man and his effect on our planet. For the average college student, or, indeed, for the average person, Hardin’s book would be an education in itself, with many literature and philosophical citations, and/or assessments of man’s situation.
