This semester I’m teaching Environmental Earth Science to a fantastic group of students at Kent State. In tomorrow’s class about fossil fuels, we’ll be talking about coal formation, use, and environmental consequences. A big one I think they should be aware of is the practice of mountaintop removal mining in West Virginia. We’ve already talked about it a bit, but I think this video gives some nice visuals, even if the narration veers a bit from overly dramatic to “boys with toys”.
From the Smithsonian:
Several well-respected scientists are working to figure out the impact of mountaintop removal mining on stream ecosystems. The coal companies haven’t exactly lined up to fund their work and provide access to the sites. So what *do* we know about the impacts of mountaintop mining on Appalachian streams and rivers? Here’s just one example, from the abstract of Bernhardt and Palmer (2011):
Southern Appalachian forests are recognized as a biodiversity hot spot of global significance, particularly for endemic aquatic salamanders and mussels. The dominant driver of land-cover and land-use change in this region is surface mining, with an ever-increasing proportion occurring as mountaintop mining with valley fill operations (MTVF). In MTVF, seams of coal are exposed using explosives, and the resulting noncoal overburden is pushed into adjacent valleys to facilitate coal extraction. To date, MTVF throughout the Appalachians have converted 1.1 million hectares of forest to surfacemines and buried more than 2,000 km of stream channel beneath mining overburden. The impacts of these lost forests and buried streams are propagated throughout the river networks of the region as the resulting sediment and chemical pollutants are transmitted downstream. There is, to date, no evidence to suggest that the extensive chemical and hydrologic alterations of streams by MTVF can be offset or reversed by currently required reclamation and mitigation practices.
Here’s an overview of the consequences and some suggested policy recommendations, presented in Science in 2010.
Among the scientists working on the environmental consequences of mountaintop removal, Margaret Palmer has become perhaps the most visible. Here she is on the Colbert Report:

Finally, here’s an profile of Margaret Palmer and her work on mountaintop removal mining, published earlier this year in Science magazine.

- What’s the connection between Kent, Ohio and mountaintop mining? Our energy company buys coal from West Virginia mountaintops. See what this looks like on Google Earth. You can use the site to find the connection for your area.
- ilovemountains.org is full of information and pleas for action from those opposed to mountaintop mining.
- Check out how Google has teamed with anti-mountaintop mining activists to show the scale of the activity.
