For example, acid rock drainage (created by the exposure of crushed rocks to air and water) can release harmful contaminants, such as arsenic, mercury, and lead. Advances in deep-sea mining may decrease those effects by reducing the demand for land-based mining. /// CHALLENGES Environmental effects.Web
