What, if the water of all the oceans becomes potable?

What if water of oceans become potable

Lack of fresh water is a global problem for all of humanity. every year this problem is felt more and more acutely. 

only 3% of the water on Earth is potable, of that most of it is essentially inaccessible as it's trapped in glaciers. 

less than half of one percent of the water on Earth is all that remains as drinkable water, to be divided among the seven billion people on the planet. 

But, what if the world's oceans were to become fresh drinkable water. 

Take a deep breath, you have to face reality and who knows how strong this information tsunami will be.

How The Sea Becomes Salty?


What If All Ocean Water Were To Became Fresh Water

So how did the oceans become salty, in the first place. 

indeed almost four billion years ago all the water on the surface of the earth was fresh. 

but volcanoes erupted spewing out countless millions of cubic meters of magma and hot gases. a chemical cocktail of chlorine, fluorine, bromine and other compounds fell into the ocean waters, in the form of acid rain. 

this rain eroded the crystalline rocks of the Earth's crust, freeing up magnesium, potassium and calcium. 

as a result of chemical reactions with solid earth and rocks. acids began to form salts. 

now there's so much salt in the oceans that if you tried to distribute it across all of the Earth's landmass. this layer of salt would be as high as a 40-story building

What Happens, If All The Water Becomes Potable?


What If All Ocean Water Were To Became Fresh Water

So let's turn back the clock! close your eyes, imagine that you're at the ocean, there's a sandy beach, a hot Sun beating down and turquoise waves lapping at the shore. 

you're thirsty, safe to just go to the ocean, you scooped up some water into your palms can enjoy the taste of crystal-clear water. 

what would happen if this fantasy could become reality. well unfortunately and there are approximately 22,000 species of fish that require both salt and freshwater. 

salmon, sturgeon, striped bass and other fish usually live in the sea and have thick skin through which salt passes with difficulty. but to spawn they must go up a river. 

but the rest of our marine inhabitants prefer one habitat and that is salt water. and there are so many more of them 230,000 known marine species and about 2 million still unknown in science.

In marine animals, tissues contain large amounts of salt. if they're put into freshwater then the salt contained in their tissues will pass out through their skin into the freshwater. 

their tissues will be damaged cease to fulfill their functions and the animals will die. as a result the food chain will collapse.

Effect On Food Chain.


What If All Ocean Water Were To Became Fresh Water

Mankind would lose one of its most important sources of nutrition. animals whose diet consists mostly of fish will die. 

about 700 million people will lose their main source of income, possibly condemning them to hunger, poverty and even death.

Desalination of the oceans will affect plant life as well. underwater algae play a crucial role in photosynthesis. the process that supplies our planet with oxygen. algae used to ocean water will die in freshwater. 

Which means that there will be less oxygen on the planet and more carbon dioxide. under such conditions the entire food chain will collapse. since most of the plants will just cease to exist. 

The greenhouse effect will intensify. the planet will overheat and the world as we know it halt in anticipation of climate shocks. hurricanes, tornadoes and typhoons all will become commonplace. the climate on the planet will never be the same. 

in the south people will begin to freeze from the cold and in the north they'll be worn out by the heat. 

With a decrease in the amount of salt. the density of water will change. which will inevitably lead to unprecedented earthquakes and volcanic eruptions. 

Freshwater is less dense, which means that the Arctic ice sheet will drop 10 centimeters into the water and the largest tidal wave that the planet has ever seen will cover the land.

But it's unlikely that a person will have to suffer for a very long time from these natural disasters. most likely man will not remain around long after the very beginning. when the world will be left without plants and marine inhabitants and climate change occurs.

So you might think this is all a little far out. 

but alas the global warming process has already started the desalination of the Atlantic Ocean. 

some scientists believe that warming will lead to a change in the Atlantic currents. which means that cold water will bring currents to the equatorial region while warm water rushes towards the poles. 

Exacerbating the melting of glaciers associated with atmospheric phenomena. due to the addition of large quantities of fresh water into the ocean. 

Traditionally cold regions may find themselves in a zone where the climate has flipped from cold to hot. if the warming continues then mankind is in for a change in climatic zones. 

scientists have not yet been able to determine the probability of such a scenario. but a professor at the University of Potsdam won Stefan Rahmstorf compares this forecast with the threat of a nuclear explosion. And even if its probability is only 5%. this is an alarm bell.  

Did You Know!


What If All Ocean Water Were To Became Fresh Water

The waters of the Southern Ocean surrounding Antarctica are already becoming diluted with fresh water. 

back in the 1970s, in the ice of the Weddell Sea. satellites recorded a huge non frozen area the size of New Zealand. but today there's no trace of it.

Experts studied a huge number of measurements taken from ships and autonomous ocean rova floats in the seas around Antarctica. over a period of 60 years to understand why this phenomenon has not appeared again.

The results showed that since 1950 the surface of the ocean has become less and less salty. this layer of fresh water on the surface of the ocean prevents mixing with the warm water underneath.

As a result heat from the depths of the ocean can't rise and melt the winter ice of the Antarctic and therefore that ice-free polymnia according to scientists may have been the last in the southern ocean.

Role Of Technology.


What If All Ocean Water Were To Became Fresh Water

But if it's impossible to desalinate the entire world ocean. might it be possible to obtain fresh water from the sea in a controlled volume.

It might seem that it would be difficult to remove, let's say 35 grams of salt from each liter of seawater wouldn't. technologies to turn seawater into freshwater do already exist. 

But despite all the efforts made. desalination of seawater remains an expensive endeavor. 

Distillation and the reverse osmosis method require a huge amount of electricity and the purification systems quickly become clogged. and therefore unusable. 

Along with the seawater, sea life also enters desalination plants. which at this time means that more than three billion fish and other marine organisms die annually.

In addition concentrated desalination waste is discharged back into the water. which adversely affects the marine flora and fauna. 

but scientists continue to work on improving this technology. in 2017 british scientists invented the world's first graphene desalination filter. which can replace existing less efficient devices. 

And in 2018 chemists from Texas and two independent Australian universities, proposed a fundamentally new technological process using organo metallic frame membranes. which will produce fresh water with minimal energy consumption and maximum efficiency.

Canadian and Australian scientists went even further and announced the possibility of using solar energy to desalinate seawater.

The Canadians only needed one kilowatt of electricity. seawater a shallow artificial pond with a black bottom and a pump to produce some fresh water.

Their Australian counterparts created a new device in the form of a disc with a surface of filter paper. special carbon nanotubes are distributed across this disc.

The finest cotton threads absorb saltwater. push crystallized salt to the edges and collect fresh water in the center of the disc.

The collected salt is then removed from the device. Thus an uninterrupted desalination process is achieved resulting in almost 100 percent efficiency.

But most importantly. the use of this device is possible at any level of sunlight. which means that it can be used in different parts of the world and not just in hot and sunny regions.

The technology of recent years has yet to prove its effectiveness when used on an industrial scale. but if everything works out then perhaps the problems of fresh water shortages will be solved.

Is it true that there are mega tons of water in the world that mankind cannot use for his own purposes? and is it true that to make fresh water you need expensive and yet ineffective technologies? I must admit.

In my opinion we shouldn't interfere with the delicate balance of the oceans. because it's uncontrolled desalination would cause the most incredible and undesirable consequences.

The best solution is to take care of the water supplies that we have now. so that our children grandchildren and great-grandchildren won't have to worry about where to get their drinking water or be shuttered and spent from unquenchable thirst.
