In the long run, resources will become scarcer and scarcer, but there is a possibility that resources will be recovered from the ocean. There is an abundance of seabed mining in shallow water, but none in the deep sea. The overwhelming vast majority of marine mining is now sand for construction materials, eclipsing all other forms of industrial activity in the oceans except fishing and oil and gas. Two principle activities going on in deep sea mining are exploration, or looking for and defining the potential resources, and developing the technology that people think will be needed for deep sea mining being carried out by private companies and countries. There is economic motivation to carry out this mining, technological advantages of ease, and it is seen as an opportunity for countries that don’t have a source of metals currently.
