Mining Operations and Environmental Impact

The video, presented by Mr. Kite, explores the topic of mining within Earth Systems. It covers key vocabulary such as crustal abundance, ore, and tailings. The video details various mining methods, including mountaintop removal, open pit, strip mining, placer mining, and subsurface mining. It discusses the environmental and human impacts of mining, highlighting issues like habitat destruction, acid mine drainage, and miner safety. The video concludes with future challenges in mining and relevant legislation, including the General Mining Act and the Surface Mining Control and Reclamation Act.
