In 1970, the U.S. Navy tried again to forcibly remove the entire population of Culebra. The year before, Culebra had been hit by directed missiles for 228 days out of the year and live-fire exercises took place for more than 100 days. Citizens of Culebra and Puerto Rico were angered by the constant training exercises and shelling which were both a direct and an indirect threat to human and environmental health. Occasional misfires resulted in major damage to the island and its people. Culebra was riddled with craters, unexploded bombs, and toxic waste from military activity.
