   It is more apparent now than ever before that coal mining, especially mountain top removal, is unethical and inhumane.

It’s time to shake off the flawed belief that we are reliant upon coal and other fossil fuels.

   Tthere have been some problems, such as some people riding recklessly, going off the designated trails, and even secretly constructing illegal trails. But those are a small minority of bulldozer riders. You shouldn't allow a small minority to give the majority of us bulldozer racers, who ride responsibly, a bad name. Why should we be punished, just because of them, and be forced to walk, just like everybody else?

9. The Impacts of Mountain Biking on Wildlife and People
   A Review of the Literature
   Resource Type: Article/Report/Letter
   Published: 2004
   It is clear that mountain biking is harmful to some wildlife and people. No one, even mountain bikers, tries to deny that. Bikes create V-shaped ruts in trails, throw dirt to the outside on turns, crush small plants and animals on and under the trail, facilitate increased levels of human access into wildlife habitat, and drive other trail users (many of whom are seeking the tranquility and primitiveness of natural surroundings) out of the parks.

    Resource Type: Article/Report/Letter
    Published: 2008
    I do not accept the premise that abuse of our lands is something that we must tolerate as inevitable. It is our land. It is our children's land, and their children's land. We have a responsibility to pass these lands on to the next generation in better condition than we found them.
    Talking about promoting 'responsible' ORV use is like suggesting we ought to promote "responsible wife abuse" or "responsible child abuse."

    The Effects of Mountain Biking on Wildlife and People
    Resource Type: Article/Report/Letter
    Published: 1997
    To most environmentalists, bicycles have always been the epitome of good. We are so used to comparing bikes to cars, that it never occurred to us that the bicycle would be ever used for anything bad. Indeed, replacing motor vehicles with bicycles deserves our adoration. But anything can be used for good or evil, and using bikes to expand human domination of wildlife habitat is clearly harmful.
