"This Crowded Earth" Review Ahead of its time in 1958, this novel's central theme of overpopulation is a crisis-du-jour whose time has come and gone. However, Bloch brings much more than that to the story: a very plausible portrayal of humanity trying to preserve the appearance of normality in the face of impending doom, unintended consequences to even the best-intentioned social engineering, and a judgement passed on the entire science fiction genre, which make the novel well worth the read. This is the first Bloch novel I've read, though his is a very well-known author and I have watched movies and television he has scripted (Psycho, Star Trek's Catspaw). Read 2010/7/7.
