Unfortunately, limestone mining can put biodiversity at risk. A limestone quarry can destroy or disrupt underground caves that are home to numerous species of life. In some cases, a species may only be able to survive in a particular cave, so a single limestone mine can wipe out an entire species. 6. Dust-Related Health Hazards
