Anonymous users2024-02-08Although this kind of thing can only be imagined, if there is a day when all the sea water becomes fresh water, then our lives will change dramatically. First of all, the most immediate point is that our cost of living will increase.
The reason why we say this is that although we say that there are more freshwater resources, in fact, we actually use relatively little freshwater resources. Even if all the seawater on the earth is converted into fresh water in the future, then the use of water in our lives is likely to no longer cause any living expenses, but this can not be said to alleviate any economic pressure on our lives at all, but once all the seawater becomes fresh water, then the pressure on life caused by other aspects is very great. One is the necessities of life, and the other is the food.
In terms of the aquatic products we eat, the aquatic products developed in the seawater every year account for an important part of the aquatic products used in our lives, and once the seawater is all fresh, then the aquatic products in the seawater will become cut off. Even if we go to artificially cultivate freshwater products, this will not be able to alleviate the problem in a short period of time. As a result, there will be shortages of aquatic products and food.
On the other hand, it is the salt **. Salt is an indispensable daily necessities in our lives, and once salt is missing, it is difficult for people to survive. And the salt we use today, a considerable part of it is obtained by drying in seawater and then purifying, once the seawater is all desalined, then the salt reserves will become very tight, which will also lead to the soaring of salt.
And the salt crisis is very serious for people. There was a time when salt was fried for ten yuan a bag was hard to find. This shows how important table salt is to human beings.

Anonymous users2024-02-05If the sea water becomes fresh water, then human salt will definitely rise wildly, you must know that the rocks on land do not contain iodine, compared to, the salt in the rock formation, the cost of sea salt is very low, and it contains iodine, so it is relatively low.

Anonymous users2024-02-03More than 70% of the earth is water, of which fresh water accounts for only a small part, so the earth's drinkable freshwater resources are very scarce, and if all the seawater becomes fresh water, it will greatly reduce the pressure on water use.
The earth's water resources are very abundant, almost inexhaustible, but the freshwater resources needed by human beings only account for the total amount of water resources, and most of the freshwater resources are frozen in glaciers, in fact, there are very few freshwater resources available to human beings. >>>More
If all the seawater becomes fresh water, it will cause many organisms in the ocean to fail to adapt and die, destroy the biological chain, and lose the necessary salt for the human body, which will also affect the survival of human beings.
Seventy-one percent of the planet is covered by oceans.
The role of the ocean on the earth is very important, and if there were no oceans and seawater, there would be no earth now, and there would be no various creatures on the earth now. If all the seawater on the earth disappears, all life on the earth will be extinct, and the earth will become a desolate place like Mars, which is what none of us want to see, so we must protect the earth and protect the ocean. >>>More
The sea water is all frozen, the first direct impact is the organisms in the ocean, the oxygen contained in the water in the ocean, a large part is integrated by the sea water when it is in contact with the air, a small part is produced by marine plants, after the sea water freezes, the sea water can not be in contact with the air, the oxygen content is inevitable, without sufficient oxygen, the death of marine animals is difficult to avoid, whales and other animals that breathe by the lungs are dead faster, the death of a large number of marine animals will definitely cause marine pollution, the ocean will become a pool of stagnant water, A pool of stagnant water that spans the globe. Marine animals that do not die of lack of oxygen may eventually die of starvation, because when the sea freezes, the activity of ocean currents will inevitably weaken, and without the surge of ocean currents, microorganisms, plankton and other bait will not be able to float in the water, and fish may starve to death without food.
Gravity will fluctuate, but that's not the main thing, and you'll fly off the ground by inertia.
