Abstract

A common metaphor on our planet portrays it as a rescue boat for life that travels in an endless see of cosmic darkness. If this metaphor is to be considered a precise one, this would mean that the earth is the only chance for life to survive the journey – at least as far as animal life is concerned. Apart from this, however, the metaphor implies that our planet is also very fragile, and that its carrying capacity is limited. Now, imagine that this boat is invulnerable to external threats; imagine, also, that it is self-sufficient and self-regulated. It is only a tiny fraction of its numerous passengers that has the power to put in danger the boat’s safety: they can do this either by multiplying uncontrollably and thus adding excessive weight to the boat, or by undertaking certain actions that could completely destroy the boat, and this despite the palpable fact that the boat’s failure will unavoidably lead all passengers to their doom, the saboteurs included. What should be done with such a bunch of foolish saboteurs, then? Why shouldn’t they just be forced out into the sea? Well, here comes an impossible inconvenience: the only ones who are entitled to judge this – and the only ones who can execute the sentence – are these very same saboteurs.
