How can we prevent deep sea mining?

How can we prevent deep sea mining?

The repair, recycling and reuse of products should be encouraged to help reduce the demand for raw materials from the deep sea. Enhancing product design to make use of less or alternative materials can also reduce the demand.

Where is deep sea mining most common?

Polymetallic nodules are found in many parts of the world’s oceans, but a large accumulation occurs in the Clarion Clipperton Zone (CCZ), an abyssal plain that stretches across 4.5 million square kilometers (1.7 million square miles) between Hawaii and Mexico in the Eastern Pacific Ocean.

Should deep sea mining be allowed?

Scientists have urged caution against deep seabed mining in the face of uncertainties about its impact on marine ecosystems. Potential adverse effects on the environment of deep seabed mining are likely to outweigh any potential benefit from increased metal supply.

What are the benefits of deep sea mining?

Why are there such valuable materials in the deep ocean? Natural hydrothermal geysers on the deep ocean floor regularly vent rich concentrations of metals and minerals from the earth’s core, forming valuable seams on the ocean floor that can yield up to 10 times the precious metals as in comparable land-based mining.

Which countries are deep-sea mining?

Countries such as India, Brazil, Singapore, Russia, Germany, Canada, United Kingdom and the United States are all moving forward with exploration plans for deep-sea mining, or DSM. The metals they are searching for include: iron, manganese, copper, zinc, lead, nickel, cadmium, silver, platinum, rare earths and gold.

Where is the deep sea located?

The average depth of the ocean is about 12,100 feet . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.

Is deep-sea mining profitable?

This is the area of greatest commercial interest, estimated to hold more nickel, cobalt and manganese than all known terrestrial deposits combined. A recent MIT cost-benefit analysis found that mining these nodules would be profitable, with annual revenues of up to US$2.2 billion a year.

How is deep-sea mining done?

Mining interests plan to use large, robotic machines to excavate the ocean floor in a way that’s similar to strip-mining on land. The materials are pumped up to the ship, while wastewater and debris are dumped into the ocean, forming large sediment clouds underwater.

Why is deep-sea mining bad?

Besides noise pollution, studies suggest that deep-sea mining will destroy habitats and marine life with sediment plumes, chemical pollution and light pollution, not only impacting the immediate vicinity, but potentially harming migratory species and key fisheries.
