The whole debate about immigration is about managing numbers. In other words, it is about meeting growing needs with increasingly reduced resources.
If we look at immigration from a technical point of view, without passion and without prejudice, the facts are staring at us. The ratio between population and resources is an unavoidable truth.
The very same operators that raise the alarm by saying that the World's population has gone beyond the mark of 7 billion - 7,000 million - and that talk about depletion of resources and damage to ecosystems are the ones criticizing us and calling us Fascists, Nazis and the like because we are raising the alarm about what is happening in Britain.
