Unfortunately even though the EPA has at least temporarily halted a lot of MTR projects for environmental studies, there are a lot of permits out there to be acted on. The website I Love Mountains keeps track of what is happening, and provides information about how to help. You can read about the new destruction at Coal River Mountain on I Love Mountains and Coal River Wind. As you can see in the video, Coal River Wind is working toward the most obvious solution - using those mountaintops for windmills instead of destroying them. This will also provide much needed jobs in a clean industry.
If you are a teacher, you can find a lot of classroom resources about mountaintop removal on I Love Mountains as well.
