Miacademy & MiaPrep Learning Channel

This educational video explores the profound environmental consequences of United States westward expansion and industrial development from the 19th century through the 1930s. Using the dramatic backdrop of the Dust Bowl as a hook, the narrator guides viewers through a historical journey that examines how human settlement, farming practices, and resource extraction altered the physical landscape. The video connects historical events like the decimation of the bison population and the clearing of forests in the Pacific Northwest to ecological principles, illustrating the direct link between human activity and environmental health. Key themes include the interaction between humans and their environment, the unintended consequences of technological and agricultural progress, and the rise of the conservation movement. The video specifically highlights the causes of the Dust Bowl, the ecological role of keystone species like bison and bees, and the political response to environmental degradation led by figures like Theodore Roosevelt. It contrasts the destructive practices of the era with the establishment of the National Park system, fostering a discussion on stewardship and sustainability. For educators, this resource serves as an excellent bridge between Social Studies and Science curriculums. It effectively visualizes abstract historical concepts through primary source photography and engaging reenactments, making the environmental costs of expansion tangible for students. The built-in pause points and guiding questions provide ready-made opportunities for classroom discussion, checking for understanding, and critical thinking about how past environmental decisions continue to shape our world today.
