What “Free Trade” Has Done to Central America

In contrast to their Central American neighbors, El Salvador and Costa Rica have imposed regulations to defend their environments from destructive mining practices. Community pressure to protect the scarce watersheds of El Salvador—which are deeply vulnerable to toxic mining runoff—has so far prevented companies from successfully extracting minerals like gold on a large scale, and the Salvadoran government has put a moratorium on mining. In Costa Rica, after a long campaign of awareness and national mobilization, the legislature voted unanimously in 2010 to prohibit open-pit mining and ban the use of cyanide and mercury in mining activities.
