During the late 19th century and the early 20th century, the United States rapidly blossoming manufacturing and building industries wreaked havoc on the nations mineral resources. To keep up with demand, billions of tons of minerals were mined, and thousands of square miles of topsoil and vegetation were destroyed. In this episode of Environment and Ecology, students learn about this damage done to land, how bioremediation is attempting to reverse these damages and what mining companies are doing to prevent future mistreatment.
