Question

Plz give me "5 lines on water pollution due to deep sea mining"

I need it plz

Don't spam or ur gonna get reported​

Answer 1

Answer:

• Deep seabed mining (DSM) is the term applied to processes and technologies designed to collect metal-rich resources from the deep seafloor.

• There are three types of deep seabed mineral resources that are of interest to mining companies: seafloor massive sulphides, cobalt-rich ferromanganese crusts, and polymetallic nodules.

• Extracting sulphides and crusts entails cutting into the seabed surface. By contrast, polymetallic nodules are rock-like accretions that lie unattached on the surface of the ocean floor and can be collected without cutting or drilling.

• Most interest and investment in DSM is focused on polymetallic nodules. They were discovered almost 150 years ago during the famous HMS Challenger expedition (1872 – 1876), the voyage credited with launching modern oceanography.

• There are trillions of these nodules, roughly the size of potatoes, lying at a water depth of 4,000 to 6,000 metres in the Clarion Clipperton Zone (CCZ), a six million square kilometre region of the Pacific Ocean’s seafloor between Mexico and Hawaii.

• Since the early 1970s, there has been growing interest in collecting these nodules due the high-grade and multiple metals they contain – metals like nickel, cobalt, manganese, and copper.

• DSM is an industry in the exploration, research and development phase. There is no commercial activity (i.e. mining) at all at present.

• Deap sea mining effect the water very badly like Water running through mine tailings can become polluted. The acid runoff further dissolves heavy metals such as copper, lead, mercury into groundwater or surface water. The rate and degree by which acid-mine drainage proceeds can be increased by the action of certain bacteria.

• therefore we should stop doing deep sea mining
