The Unsustainable Use of Sand: Reporting on a Global Problem
Sand is considered one of the most consumed natural resource, being essential to many industries, including building construction, electronics, plastics, and water filtration. This paper assesses the environmental impact of sand extraction and the problems associated with its illegal exploitation. The analysis indicates that extracting sand at a For More Information. Sand is critical to fracking. After workers drill down into rock, they create fractures by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released. Frac sand mining creates significant air pollution from the handling, mining, and processing of the sand.Frac Sand Health and Environmental Impacts Earthworks
