Environmental Impacts and Mining Risks

The video discusses human impacts on the lithosphere, focusing on mining, drilling, urbanization, and shoreline development. It covers various mining methods, their environmental effects, and the risks associated with uranium and plutonium mining. The video also explores the impacts of oil and natural gas drilling, including fracking, and highlights the consequences of urbanization and landfill issues. Finally, it addresses human activities on shorelines and their effects on coastal erosion.
