The yellow precipitation falls due to the stable and constant sleep in the sea. This point must be taken into account in the process of calculating pure sea salt.



The volume of water in the Black Sea is 555,000 cubic meters. by km. Or 5, 55 x 10^17 liters.

The volume of urine released by an adult person per day is an average of 1.5 liters.

That is, in order for the percentage of urine in the sea to be some significant value (say, 0, 1%), a person should suck in the sea for a day 4 x 10^13 degrees.

Population of the earth 7, 8 x 10^9.
