Not what you were expecting:
Yes: nuclear waste. As soon as the government was gone, mysterious European ships started appearing off the coast of Somalia, dumping vast barrels into the ocean. The coastal population began to sicken. At first they suffered strange rashes, nausea and malformed babies. Then, after the 2005 tsunami, hundreds of the dumped and leaking barrels washed up on shore. People began to suffer from radiation sickness, and more than 300 died. Ahmedou Ould-Abdallah, the UN envoy to Somalia, tells me: "Somebody is dumping nuclear material here. There is also lead, and heavy metals such as cadmium and mercury - you name it." Much of it can be traced back to European hospitals and factories, who seem to be passing it on to the Italian mafia to "dispose" of cheaply. When I asked Ould-Abdallah what European governments were doing about it, he said with a sigh: "Nothing. There has been no clean-up, no compensation, and no prevention."
At the same time, other European ships have been looting Somalia's seas of their greatest resource: seafood. We have destroyed our own fish-stocks by over-exploitation - and now we have moved on to theirs. More than $300m worth of tuna, shrimp, lobster and other sea-life is being stolen every year by vast trawlers illegally sailing into Somalia's unprotected seas. The local fishermen have suddenly lost their livelihoods, and they are starving. Mohammed Hussein, a fisherman in the town of Marka 100km south of Mogadishu, told Reuters: "If nothing is done, there soon won't be much fish left in our coastal waters."
