What Is Deep Sea Mining? (with Picture)

deep sea mining is the process of removing valuable materials such as metals and minerals from deposits located at the ocean floor or the floor of other large bodies of waters. this method of mining is relatively new as compared to mining on dry land, and the environmental impact is a concern among environmentalists and governments, as well as industries that rely on the oceans and waterways.
