In Colombia, oil resources are only one reason for the ongoing armed conflict. The Colombian military and the paramilitaries also battle guerrillas over the control of coca-producing regions that provide 90 percent of the cocaine reaching the United States. Civilians account for up to 75 percent of the conflict's victims.
