With the signature of President Salvador Sánchez Ceren, El Salvador on April 27 became the first country on Earth to ban the mining of metals—following a long campaign by campesinos and their ecologist allies. The law, passed by the country's Legislative Assembly March 29, bans "prospection, exploration, exploitation, extraction or processing of metallic minerals in El Salvador." Mauricio Sermeno, leader of the Salvadoran Ecological Unit (UNES), said the law "is necessary in the face of an industry which, far from bringing any benefit to communities, brings serious pollution to water sources and the environment."
