It is one of the most remarkable things that in all of the biological sciences there is no clue as to the necessity of death. If you say we want to make perpetual motion, we have discovered enough laws as we studied physics to see that it is either absolutely impossible or else the laws are wrong. But there is nothing in biology yet found that indicates the inevitability of death. This suggests to me that it is not at all inevitable, and that it is only a matter of time before the biologists discover what it is that is causing us the trouble and that that terrible universal disease or temporariness of the human's body will be cured. Anyhow, you can see that there will be problems of a fantastic magnitude coming from biology.

There is no law of biology that says things have to die.

Let us again look at the laws of thermodynamics. It is true that at first sight they read like the notice at the gait of Dante\'s Hell; but in fact, tough as they are and although like income tax they cannot without penalyt be evaded, they can with forethought be avoided. The Second Law states unequivocally that the entropy of an open system must increase. Since we are all open systems, this means that all of us are doomed to die.

He gets this backwards. The Second Law only applies to closed systems. We and our planet are not closed systems, we are open systems; therefore, mortality is not required of us. In fact, the second law states that, so long as we can keep exporting entropy by taking in energy from outside sources, we can live forever.
