JEMA: As day broke in a remote part of western Ghana, a priest, farmers and other residents combed through the forests, looking for signs of illegal gold mining. They have done this for the past year as part of a grassroots task force created to combat the mining that has poisoned rivers in one of the world’s largest gold producing countries. The group is also driven by the sight of Ghana’s unemployed youth being attracted to illegal mining and the elusive promise of quick wealth.
