Earlier this year, I had the opportunity to travel to Cabañas, El Salvador, to meet with some of the bravest and most successful environmental activists in the world. Ordinary villagers in this remote area of the country have joined with religious groups, research centers, and others to take on the powerful international mining companies that are seeking to plunder their country’s gold. So far, the activists have been winning this David-vs.-Goliath fight. Two successive Salvadoran governments have denied permits for gold mining on environmental and human health grounds.
