Dune by Frank Herbert is an obvious choice for resource politics, and environmental politics. It's also a great tale of religion and power, so relevant in many ways.

I highly recommend Nancy Kress's books to see the potential impact of biotechnologies on man, politically. Start with Beggars in Spain; there are two sequels if you enjoyed it, and several other books by her.

Fooled by randomness by Nassim Nicholas Taleb, and several books by Michael Lewis (Liar's Poker is well known and a bit old, but still worth it, and hismore recent books are all easy to read and very interesting) and Po Bronson (especially Bombardiers) are good introductions to how our financial markets work (which means, how they exploit other people's ignorance and put us all in danger).

In the long run, we're all dead. John Maynard Keynes
