To avoid the worst impacts of climate change, scientists contend that the world needs to reach net-zero carbon dioxide emissions by 2050. The United Nations recognizes that renewable energy is the key to achieving this goal. But scientists state that the necessary green energy infrastructure cannot be built without rare earth elements, such as cobalt, nickel, and …

Deep-sea mining is an emerging industrial activity in climate tech involving the extraction of minerals and metals from the ocean floor at depths ranging from 200 meters to 6,500 meters. Deep-sea mining technology is still in the experimental stage and no commercial mining has been done yet.

The mining industry is one of the largest-scale industries in many countries (Jafarpour and Khatami, 2021), contributing billions of dollars to the economies of countries and the world (Ren et al., 2022).Ore mining involves extracting precious mineral resources that are naturally present in the earth's crust.

At present, fluid jet machines are used to pick up nodules from the deep-sea bed. These machines carve out 15 cm sea-bed sediment layer from which the unwanted sediments containing heavy metals are pumped back into the sea, smothering life beneath and burying an essential part of the food chain. As a result of such sea pollution, a significant ...

Why river machines should top a list of ocean clean-up technology may come as a surprise: 80 percent of marine pollution comes from land. Most of that is called "non-point source" pollution, which is anything that ends up in waterways that runoff into the ocean, according to the US National Oceanic and Atmospheric Association.

Deep Sea Mining. The three main mineral resources (Hein et al. 2013) in Deep Sea Mining are: Polymetallic nodules (rich in manganese, cobalt, copper, nickel, and rare elements) on abyssal plains (between 4,000 - 6,000 m deep). Cobalt-rich crusts on seamounts (between 800 - 2,500 m deep).

The deep sea is a biodiverse habitat, home to unique creatures found nowhere else on Earth, from the dumbo octopus to the faceless cusk. Given the absence of sunlight in the deep sea, many marine organisms there use sound to navigate, communicate, find mating partners, locate food, and detect predators and other dangers and, therefore, may be sensitive to noise …

In my opinion, the cost of this disruption outweighs the benefits that are provided by Deep Sea Mining. However, if Deep Sea Mining were to change to the point where it is heavily regulated and prioritizes the marine ecosystem, then I would say it should be allowed.
