There are few places more dangerous on earth than Central America.
Endemic gang violence and poverty has always been blamed for forcing hundreds of thousands to head north to find sanctuary in the United States.
The migrants have been routinely politicised as a fundamentally criminal rabble intent on exporting their violent lives and culture to America.
But new analysis of the root causes of the migration shows that there is a greater, far more unpredictable and far more serious reason driving the mass movement of so many people.
Rather than escaping gangs and corruption, some of the migrants are from what is known as Central America’s Dry Corridor.
They are fleeing drought and severe food shortages caused by the growing global climate crisis.
