[laughter] >> you know what my staff gave me for christmas last year? two, not one, two and farms. [laughter] >> i have one on my desk at the presidential library and one in my office in harlem. why? because i'm always telling them that the most important political book that no one read or read for political book written in the last 10 years that would have made us all much healthier as citizens is "the social conquest of earth", less

than 250 pages long and a double pulitzer prize-winning microbiologist that first told me the combined weight of all the ants on earth is greater than the combined weight of all the people on earth. that's quite a number of ants.

[laughter] >> look, i get it dick we can make these jokes. every parent in this audience, name me one threat to that you wouldn't take seriously if you thought the odds of doing this for more than 90% better than the odds of doing that? see that child in the back seat,

100% chance your child will survive a crash unless the car completely collapses. 5% of people say, now that's crazy. they are just about as good. just throw the kid in the backseat and let them roll around. no one would do that; right? that's what we are doing on climate change. we are throwing a kid in the back seat and letting them roll around. >> you can watch the full discussion of the social conquest of earth on our website, book tv.org. book tv, television for serious readers. >> welcome to the 33rd annual chico
