Marine mining is the process of extracting valuable minerals and resources from the ocean floor. This includes materials like sand, gravel, and metals such as gold and copper. The mining can occur in shallow coastal areas or deeper ocean regions, often using specialized equipment to reach these resources. The practice raises environmental concerns, as it can disrupt marine ecosystems and habitats. Regulations are in place in many countries to manage the impact of marine mining, ensuring that it is conducted responsibly while balancing economic benefits with ecological preservation.
