The twentieth century has marked a clear watershed not only in mankind's social history but in its very destiny. The outgoing century is different from those that preceded it in that, for the first time ever, mankind cannot regard itself as immortal, for it has become aware that its dominion over nature has limits and may even threaten its own survival. Even if nuclear war can be avoided, the threat to mankind will remain, for the Earth may one day no longer have the capacity to bear the burden of human activity.
