May 20, 2019· Scientists fear impact of deep-sea mining on search for new medicines Bacteria from the ocean floor can beat superbugs and cancer. But habitats are at .
• Deep-sea mining is the process of retrieving mineral deposits from the deep sea – the area of the ocean below 200 m. • Depleting terrestrial deposits and rising demand for metals are stimulating interest in the deep sea, with commercial mining imminent. • The scraping of the sea floor and pollution from mining processes can wipe out entire species – many yet to be discovered.
For deep-sea mining contractors, who may operate large vessels for prolonged periods over a relatively small area of the seafloor, these results provide one more potential environmental impact for miners to be aware, as well as an opportunity to investigate potential environmental offsets in the form of recovering plastic waste from the ...
Dec 05, 2019· Impact on deep-sea organisms. Life on the ocean floor moves at a glacial pace. Sediment accumulates at a rate of 1 millimeter every millennium. With such a slow rate of growth, areas disturbed by deep-sea mining would be unlikely to recover on a reasonable timescale.
Aug 16, 2020· The studies that have been done on the impacts of deep sea mining show that it could seriously threaten biodiversity and disturb microbes that sequester greenhouse gases like carbon and methane, which could potentially have negative consequences for the climate crisis.
The Issue: Terrestrial mining activity produces large volumes of waste, formed by the non-processed rock from overburden or access tunnels and shafts, and by the processed tailings. Tailings are the waste produced after extraction of the targeted metal from the ore through crushing and milling. This process produces particles that consist of one mineral and separates the minerals by their ...

Aug 18, 2020· Mining the ocean floor for submerged minerals is a little-known, experimental industry. But soon it will take place on the deep seabed, which belongs to everyone, according to international law.
Apr 01, 2020· 1. Introduction. The carrying out of environmental impact assessments (EIAs) is a general obligation under customary international law, and under the UN Convention on the Law of the Sea (UNCLOS, Articles 165(2) d, f, h and 206), reflected in Article 6 of the European Treaty. In the Area (beyond national jurisdiction), EIAs are required to be carried out for mineral exploration activities ...

Apr 29, 2020· The environmental impact of deep-sea mining is only partially known. Also, there is a lack of standards to regulate mining and set binding thresholds for the impact on the local organisms.
But DeepGreen's recent claim that deep sea mining would entail minimal toxic tailings and be far less damaging to the environment than land-based mining has raised the hackles of environmentalists. Catherine Coumans of Miningwatch Canada said the scenario DeepGreen presented was more risky than for land-based mining, where its impacts are much ...
