In Guazapa, a region that was bombed heavily with napalm, CESTA worked closely with young people to create a living monument to peace. The goal was to rejuvenate the barren environment by planting a tree for every person who died during the war. Over 65,000 fruit bearing and medicinal trees have been planted in this “Forest of Reconciliation.”
Navarro has been outspoken on a number of national issues including waste trafficking. On national television in 1993, he successfully condemned a proposal to transfer old tires from New Orleans to El Salvador where they were to be burned. Navarro also led an initiative to save El Espino, one of the few forested areas left near the capital, San Salvador, and an important source of the city’s water. He asked the legislative assembly to declare the forest, which local politicians wanted to turn into a housing development, a protected zone. Development in El Espino forest was put on hold. Navarro received numerous death threats because of his work.
