What would happen if all the seawater on Earth were turned into fresh water?

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.

In order to solve the problem of fresh water shortage, many coastal countries are vigorously developing seawater desalination technology, such as Singapore, Saudi Arabia, the United Arab Emirates, Israel and other countries have made good achievements in this regard.

desalination plant).

However, desalination requires a lot of energy, and the desalination of super-concentrated wastewater has many adverse effects on the surrounding marine environment, which are the bottlenecks that limit the development of desalination.

In this regard, people have a very good wish, hoping that the sea can be turned into fresh water, so that the water problem that plagues mankind will no longer exist.

But if the sea does turn into fresh water, it will not be good for the life of the earth.

First of all, the freezing point of saltwater is lower than that of freshwater, which means that freshwater is more likely to freeze, for example, the Yellow River is easy to freeze in the cold winter, but Qingdao and Yantai at the same latitude will not freeze.

If the world's seawater turns to fresh water, then the area of ocean ice will be larger in winter, and the ice of the ocean will reflect more sunlight and heat, leading to a decrease in global low temperatures, and even triggering ice ages, which is a veritable catastrophe for life on Earth.

Once the ice age is reached, most living things will be wiped out, and human civilization will also suffer a heavy blow).

In addition to triggering global cooling, if the oceans were to become all freshwater, the oceans would become less fluid and the seas would become stagnant waters.

The ocean, like the river, is constantly flowing, called ocean currents, and the difference in the density of sea water is one of the reasons for the flow of the ocean.

In fact, the density of seawater varies from place to place on the planet, for example, the salt content of the Mediterranean Sea is higher than that of the Atlantic Ocean, so the density of the Mediterranean Sea is also higher than that of the Atlantic Ocean.

Due to the difference in the density of the seawater, the density flow of the two seas, the high-density seawater of the Mediterranean enters the Atlantic Ocean from the lower layer, and the low-density seawater of the Atlantic Ocean enters the Mediterranean Sea from the upper layer, and this exchange promotes the exchange of heat and nutrients, prospers the ocean, and also has a beneficial effect on the terrestrial climate.

If all of them were freshwater, the water would become less fluid, the ocean would not be able to deliver enough warmth and precipitation to the land, and the land would become barren.

Sea temperature and density are the main drivers of ocean currents).

In general, the conversion of seawater into freshwater is very detrimental to the ecology of the earth, and even has catastrophic consequences. If we want to solve the problem of fresh water shortage, we should start by saving and protecting freshwater resources.

From the perspective of the marine ecological environment, the sea water has turned into fresh water, which will undoubtedly bring some damage to the earth's marine ecological environment that is difficult to recover. First, marine organisms and species that are accustomed to living in seawater die due to sudden changes in their environment. Then, the integration of the freshwater environment into the seawater can also have indelible damage.

If the earth's seawater becomes fresh water, humanity will not need to worry about the problem of freshwater resources. But the impact on marine life is enormous, with the vast majority of marine life likely to die and become extinct, devastating to the planet's biodiversity.

It will greatly change the ecological environment of the earth. If seawater turns into fresh water, many marine life will not be able to exist.

What would happen to the world if all of the Earth's waters were turned into fresh water?

All the creatures in the sea die, which leads to the contamination of the water because the dead creatures will rot and carry germs.

If all the seawater on the earth becomes fresh water, then this situation is more harmful to the earth, because some species in the seawater will become extinct. Whether it is some animals or some oceans, plants will become extinct, and the environmental damage to the whole planet is very serious.

The extinction of marine life, the imbalance of the earth's ecological environment, the destruction of the integrity of the ecological chain, and the degeneration of marine resources may lead to subversive changes in the entire earth.

Third, the impact must be far-reaching and enormous. The last point is that the impact is very far-reaching, because the development of the planet involves all aspects, including human beings. If humans use all these water resources into our lives, how will other creatures on the earth live?

All the seawater on the earth has become fresh water, which will have an impact, and this impact is still very large, because the animals living in the ocean rely on seawater to maintain life, and if all of them become freshwater, it will directly lead to the extinction of the organisms in the ocean.

The impact is huge. Because if all the seawater on the earth turns into fresh water, marine life will not adapt and die, which will inevitably cause serious ecological problems and have a very large impact.

If all the seawater on Earth were to become freshwater, this situation would have an impact and could lead to the disappearance of many species. The decline in the diversity of species is likely to lead to the deterioration of the earth's environment and the extinction of human beings.

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.

If all the sea water were to turn into fresh water, the marine life on Earth could die as a result. This will cause great damage to the planet's biodiversity, but at the same time, the number of freshwater organisms on the planet will increase. For human beings, there are more water sources that can be directly used, and it is also more beneficial to the cultivation of crops.

The ocean is very important to the earth, the ocean accounts for 71% of the earth's area, life on the earth is born in the ocean, if the sea water becomes fresh water, it is equivalent to the ocean becomes a large lake, first of all, countless organisms in the ocean are likely to be extinct, all kinds of bacteria and microorganisms will slowly breed, the salt we usually eat will also become a luxury, and the health of human beings who cannot afford the price of salt will also have problems, and the environment of the whole earth will also change drastically because of the absence of the ocean. It is also very likely that humanity will die out as a result of environmental changes.

Then we won't be able to eat a lot of seafood anymore, and at the same time salt will become very expensive, or even no salt to eat, and then we will sweat very little, and we will have weakness in our limbs, hallucinations, etc.

Zooplankton and phytoplankton will become extinct as a result, leading to the extinction of a large number of marine life. In addition to this, phytoplankton can produce half of the world's oxygen through photosynthesis, and without them, we would be breathing much less oxygen.

When the seawater becomes depleted, the microorganisms in the ocean will lose their living environment, the seawater will lose its antibacterial ability, and the marine organisms will be prone to diseases, and the pollution to the ecology will become greater.

What would happen if all the seawater on Earth turned into fresh water?

I believe that friends who have studied biology in junior high school know that many places on the earth are facing the problem of water shortage. Therefore, some people can't help but wonder: if all the seawater on the earth turns into fresh water, wouldn't this solve the problem of water shortage?

If there was a technology that could turn all the seawater on Earth into fresh water, would that be a good thing or a bad thing?

From the Earth** photographed by satellites in outer space, it can be seen that the surface of the Earth is blue and looks like a water ball in space. It is also true that about three-quarters of the Earth's surface is covered by water, and the total volume of water on Earth is about 1,386 million cubic kilometers. Some of this massive 1,386 million cubic kilometres of water is found in the oceans.

In other words, the water on Earth is seawater, and the salinity is extremely high, and it cannot be directly used by humans.

If there is such a technology that can turn the world's seawater into fresh water, then not only can the current water shortage problem of mankind be solved, but the water shortage of mankind will not be repeated for tens of thousands of years. This seems like a great thing.

However, if all the planet's seawater were to become freshwater, tens of millions of plants and animals that depend on the marine environment would become extinct because they would lose a suitable habitat. If the worst consequence of the extinction of marine animals is that humans can no longer eat delicious seafood, and will not disrupt the food chain of terrestrial organisms and affect terrestrial ecosystems, then the extinction of marine plants will bring earth-shaking changes to the earth's ecosystem.

Without the oxygen released by marine plants, the concentration of oxygen in the atmosphere is bound to change. Such changes will first affect the organisms around the ocean, and then further affect the survival of other organisms on the planet. As we all know, human beings are a part of the earth's ecosystem, and when there is a problem in any part of the ecosystem, human beings will not be able to stay out of it.

In addition, many creatures in the ocean have extremely high medicinal value, and without the treasure trove of the ocean, many diseases that could have been extracted from marine organisms will become incurable. I believe that such a situation is not what everyone wants to see, so even if such a technology is really developed, it is not a reasonable plan to change nature arbitrarily, and everyone should save water resources in a down-to-earth manner and save some water for future generations.

When the earth's seawater becomes fresh water, the specific heat capacity decreases, the ability to retain heat energy decreases, and the temperature difference between day and night on the earth becomes larger.

Due to the sudden change or mutation of marine life, the death of a large number of marine organisms may pollute the marine environment, and human air quality may also decline.

Most of the creatures in the ocean will die as a result, because a sudden change of living environment can cause discomfort.
