20 million tons of gold in the ocean

There is a lot of gold in the ocean and it is possible to extract gold from seawater.

However, currently there isn’t a cost-effective way to mine or extract gold from the ocean and make a profit from it.

Why?
Because as you know, the oceans are huge, and the actual concentration of gold in seawater is only about 0.0000000006%. To put it another way, there is between 0.1 and 2.0 mg per ton, depending on location, which means that with current technology is more expensive to extract than the value of the gold extracted itself.
