Although humans are by no means a threatened species on this planet humans are obviously
concerned and fearful that mankind will not survive and that the animal species Homo sapiens
will be annihilated forever. This seems to be a contradiction. In this book the author shows
that this apparent contradiction is not one. The author shows that the fear of humans that
mankind could be annihilated in whatever way is undoubtedly justified and that this fear is not
just the unfounded imagination of a species that is apparently more or less so overwhelmed with
its own existence that it constantly fantasises about its own demise. However if this fear of
humans that mankind could be wiped out by whatever events is actually justified then a
question immediately arises the answer to which is so to speak the purpose of this book:
What would be the conditions that would have to be fulfilled so that under all possible
circumstances and for every conceivable case this annihilation of all mankind could be
prevented or avoided and there would therefore be no end of mankind? In accordance with the
subtitle of this book the author will therefore make speculations about the conditions under
which the continued existence of the animal species Homo sapiens and thus also of Mankind could
be guaranteed under all possible circumstances and for every conceivable case.
