In the meantime there is a danger that the type of adventure tourism we have been describing in this book will grow at a rate that is unsustainable in resource terms The various resources that adventure tourism uses(for example Iandscape biodiversity remoteness and culture)are susceptible to degradation through overvuse and systems need to be negotiated and put in place to help reduce this This will require different mind sets as society has often treated these resources and qualities as free goods Indeed the restrictions on commercial use of open access land specified in the countryside and Rights of Way Act(2000)highlights the issue of whether organizations that use the resource for commercial purposes such as outdoor pursuits should contribute to its upkeep Despite the active debate on sustainable tourism it is our belief that the philosophy of sustainable develoment will constrain growth of adventure tourism in only a relatively minor way in the short term.
