There are believed to be between 20 and 40 million illegal immigrants in the world.
One of Italy's top anti-Mafia magistrates says Albanian gangsters are taking control of organised crime on both sides of the Adriatic.
The most lucrative commodities are illegal immigrants.
Last week, two Italian policemen were killed as well as two Albanian smugglers, in a chase and collision in the Adriatic.
It is in this region - amid reports of more clandestine landings - that the police scour the beaches.
Large scale trafficking
However, the coast is so vast that only a small percentage of illegal immigrants are caught.
Reliable figures on the scale of people smuggling are hard to come by.
There are believed to be between 20 and 40 million illegal immigrants in the world.
Several million are believed to be in Italy, Greece, Spain, Portugal and Germany.
Italian warships are highly visible in Albanian ports in a vain attempt to deter clandestine operations.
However, Italian commanders told me they have no powers to intervene, let alone use force.
One of Italy's top prosecutors, Cataldo Motta, who has identified Albania's most dangerous mobsters, says they are a threat to Western society.
"Albanian organised crime has become a point of reference for all
criminal activity today," he says.
"Everything passes via the Albanians. The road for drugs and arms and people, meaning illegal immigrants destined for Europe, is in Albanian hands."
When the prosecutor leaves his office, three police bodyguards are at his side because of the risk of assassination by Albanian gangsters.
Child labour
The latest pawns of the people smugglers are children.
The Italian authorities will not order the enforced repatriation of anyone under 18 and the gangsters are aware of this.
At a transit camp for illegals from all over the world, 35 young Albanian teenagers are being prepared for life in Italy.
They were consigned to smugglers' boats by their families.
Roberto Matrandold, a psychiatrist, says that the children suffer from stress.
"The stress comes from the voyage itself which is more and more dangerous," he says.
In Rome, at a Vatican-sponsored convention, delegates heard warnings about far greater numbers of illegal immigrants in the years ahead.
Laura Balbo, an adviser to the prime minister, says that Italy wants co-ordinated European action.
"I think it is the biggest problem we face in Italy and in Europe because there's so much money being made which was not the case before," she says.
"It has become the main source of money for organised crime."
"So it is hard to imagine how we can fight this kind of international organisation."
Public attitudes towards illegal immigrants are hardening.
They are blamed for rising crime. In fact, Italy is chronically short of workers because of its falling birth-rate and growing economy.
Paradoxically, as operations intensify against people smugglers, the door is about to be opened for many more legal immigrants.
