Using a case study approach, this lesson examines colonialism as an ongoing force affecting nature, culture, and society by focusing on decades of tribally led efforts resulting in recent federal approval of four Klamath River dams. Chinook Salmon are not only endangered keystone species among the Pacific Northwest, but they also play invaluable roles to the communities that rely on them. Using the Four-Dimensional Ecology Education Framework (4DEE) combined with aspects of environmental sociology, this module encourages students to critically examine the causes and consequences of salmon population decline. Further, students will evaluate the decision-making involved in the largest dam removal by critiquing different stakeholder perspectives through a role-playing activity. With the conclusion of this module, students will recognize the opportunity imposed by climate change as a vehicle for social action and the integration of various forms of knowledge as a driver in making more equitable ecological decisions for our futures.
