i normally dont share things that are commercially available, but this is just too important of a work, and i think it needs to be spread around as much as possible.
(trying not to sound corny or over-dramatic but don't know how else to put it: the survival of our species is on the line)
for those who don't know, it's a book about the collapse of past civilizations -- how societies choose to survive or shoot themselves in the throat. for instance the chapter on how the Vikings in Greenland all starved and froze to death after living there for 500 years is really interesting... and he says something like "before you start laughing at the vikings, should remember that they survived in Greenland longer than europeans have survived in N. America. another highlight is when societies in the Solomon Islands descended to cannibalism, a popular insult was "I pick pieces of your mother from my teeth"
i love audio books don't you just? (thanks to Chris for hooking it up)
