   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?

   A Review of the Literature
   Resource Type: Article
   First 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.

    First Published: 2010
    The meat-producing system Simon Fairlie advocates differs sharply from the one now practised in the rich world: low energy, low waste, just, diverse, small-scale. But if we were to adopt it, we could eat meat, milk and eggs (albeit much less) with a clean conscience.

    Resource Type: Article
