· For example, some environmental impacts associated with using sand and crushed limestone, such as loss of biodiversity and land degradation, can be avoided by substituting Red Sand. Also, the use of Red Sand for road construction and top dressing is expected to conserve land and raw materials for future generations, thus enhancing intergenerational social equity.
