Can We Mine the Vast Gold Treasure Hidden in the Oceans?
The ocean contains a huge amount of gold, about 20 million tonnes, worth trillions of dollars.
However, the gold is spread out in tiny amounts, making it difficult to collect.
It comes from eroded land, underwater vents, and wind.
Scientists are trying to figure out how much gold is in the oceans and how it moves around.
Extracting it is hard because the gold is so diluted, and current methods are not economically viable.
Though mining ocean gold isn't realistic now, studying the process helps us understand how our planet works.
Scientists estimate the oceans hold 20 million tonnes of gold worth over $2 quadrillion.
The gold is dispersed in microscopic traces, making extraction difficult.
Gold enters the ocean via land erosion, hydrothermal vents, and wind.
Mining the gold faces challenges including low concentration and environmental concerns.
Researchers are studying how gold cycles through the oceans.
