When environmental engineer Richard Fuller contacted me in June, I was in New Orleans covering the oil spill, which I thought was the biggest man-made disaster of the year. But Fuller was battling a different catastrophehundreds of children dying in rural Nigeria, their blood poisoned by catastrophic amounts of lead. A gold rush in the northern state of Zamfara had led villagers to grind ore by hand and, in the process, release massive amounts of lead dust into the water and soil. "It's the worst lead-contamination event we've ever seen," Fuller says, alarm cutting through his soft Australian accent. "This is true environmental disaster."
If you didn't know about Zamfara, you're not alone. The low priority that the worldincluding the mediatends to place on toxic pollution in developing countries is one of the reasons Fuller founded the nonprofit Blacksmith Institute in 1999. Having worked for the U.N. to establish rain-forest preserves in Brazil, he was looking for a green cause that would provide maximum output from minimum input. He zeroed in on toxic contamination, especially from metals like lead, mercury and cadmium. Thousands of old lead smelters, unregulated mines and other chemical spewers are causing direct and measurable misery to local residents who can't afford to clean them up. "There's a finite number of polluted sites out there, and you can fix them for relatively little," says Fuller.
This summer his nonprofit sent a team of experts to Zamfara to help oversee the removal of polluted soil and educate villagers to prevent the disaster from happening again. The Blacksmith Institute has completed 50 such projects around the globe and is working on more than 40 others, often using low-cost tools like worms and molasses to suck up soil contaminants. It's not glamorous environmentalism; there are no poster-worthy polar bears or lush rain forests involved. Fuller's work takes place in urban slums and ravaged villages, where he is quietly demonstrating how we can save millions of the world's poorest people from long-term health problems and early death. We just have to pay attention.
