To meet rising demand without exacerbating existing quarrying conflicts in areas such as the Mendip Hills, the Government is encouraging coastal superquarry development in Scotland and elsewhere. Rather than exporting the environmental consequences of minerals extraction from England and Wales, however, the Government should tackle the root cause of the problem.
This entails finding ways of reducing the demand for aggregates and encouraging society to be more 'minerals efficient'. Take John MacGregor's roads programme. The Council for the Protection of Rural England has recently published research suggesting that the minerals needed for the national roads programme up to 2025 would require a hole the size of Oxfordshire more than a metre deep. A similar calculation could be done for the number of Scottish mountains required.
Until the Government reduces the rate of road-building and develops other policies to make us more 'aggregates efficient', we can expect to see the tragedy on Harris played out many times.
