After the war in Somalia, the ocean waters off of the country's coastline became a dumping ground for toxic chemicals that killed the fish that the local people relied on to eat. Children were dying of pollution, not in some abstract way, but quite literally. In fact, it was not just children. Adults died of the pollution also.
Deprived of a means of support, a few of the local people turned to piracy.
That doesn't make it right, but we must understand that when a nation is cast adrift it can become a target of international illegal corporate behavior.
The root of the piracy problem is ecological. We can't keep dumping in the oceans as some kind of infinite waste bin without consequences. People are already suffering with disease and no fish to eat. This is unacceptable.
