Conflict about control of resources in the rainforest is played out every day all over the world. In November 1999 in Seattle, Washington, environmentalists gathered outside the World Trade Organization meeting to protest oil drilling by Occidental Petroleum on ancestral land of the U'wa tribe in the South American country of Colombia. The U'wa tribe has requested that the Colombian Ministry of the Environment deny Occidental's request for a drilling permit. In this lesson, students will stage a mock court hearing about this issue.
