MTB Trail Riding is often touted as an environmentally friendly activity, but what about the broader impact of the sports growth and popularity - are the increased trail maintenance costs, erosion, and habitat disruption caused by the sheer number of riders outweighing the benefits of getting people outdoors and engaged with nature, and should we be implementing measures to limit trail usage and mitigate these effects, or is this just a case of eco-guilt and we should be focusing on more pressing environmental issues, and if so, what are some practical solutions to balance the needs of trail users and the environment, or is the real problem the fact that many trail systems are not designed with sustainability in mind and we need to be rethinking the way we build and manage trails from the ground up.
