Humanity consumes 17.5 billion tons of water every day, what will happen to the total amount of wate

We know that the earth is rich in liquid water, and there are large quantities of liquid water resources in the five oceans of the earth. According to statistics, the total amount of water reserves on the earth is about 100 million cubic kilometers, which seems to be a very large number. But another statistic shows that the average daily water consumption per person on the planet is 25 cubic meters, and there are currently about 7 billion people on the planet, so the daily water consumption of humans on the planet is about 100 million cubic kilometers.

In this regard, scientists say that although the earth's water resources are constantly being consumed, the total amount of water resources on the planet has not decreased. Why is that?

Scientists explain that, like most things in nature, water follows the law of conservation of mass, which means that water does not arise out of thin air and does not disappear out of thin air. It may change from one form of matter to another, such as from a liquid state to a solid or gaseous state, or it may be transformed into another substance under the action of some external factors, but it never disappears. Back in real life, we need to drink water every day, and at the same time, we also have a variety of excretory reactions every day, those water that we use up or are excreted from the body with human excretion and return to nature; Or temporarily stay in the human body, continue to participate in various reactions in the human body, but after all, it does not disappear.

In addition, there are some water resources that have not been exploited and used by humans, and even if they never flow into the food chain and are never used by organisms, they will not disappear from the earth, they may move places, or they will change forms, but they will still stay in a corner of the earth. So, even though we consume the earth's water resources every day, the total amount of water on the earth is not decreasing.

We need to drink water every day, and at the same time, we also have a variety of excretory reactions every day, and the water that we use up or is excreted by humans and returned to nature; Or temporarily stay in the human body, continue to participate in various reactions in the human body, but after all, it does not disappear.

It won't change because it will be evaporated into the air and rain will fall.

The total amount of water does not change because water in nature is used in a circular form.

The total amount does not change because the water is recycled.

It is a waste for many countries with extreme water scarcity, and in general the earth's water resources are not very large

It is believed that there is no life without water, and the role of land is to provide other substances for life. and the carrier of life.

If we waste water like this, we will explode and lose life due to lack of water. It is also because the total amount of water on our earth does not change. When we drink what is in our body, we will expel it.

Because water purification is very difficult, you can see how hard it is to filter seawater, it's not as easy as you think, and it's like Beijing and other places are far away from water sources, there are more people, and the per capita water resources are very small, and domestic wastewater is indeed discharged into the sea.

The total amount should be constant, because the water on Earth is always in a state of equilibrium through the natural cycle and does not disappear for no reason.

I think it's possible that this water will evaporate deep in the earth and return to the surface as water vapor, or it may connect with a trench in the depths of the ocean and flow back to the sea.

This seawater flows into the interior of the earth, collects into groundwater, and sometimes flows back to the surface, which is a cyclical process.

The water did not disappear, but returned to the sea in another form. For example, in volcanic eruptions, magma is actually another form of water. In addition, although the water flows into the interior of the earth, it still evaporates back into the atmosphere.

All this water is in the interior of the earth, so some of it is also evaporated. So you can say that there can be a small part left, and as for those that are gone, it's a process.

It may have gone elsewhere through underground rivers, and eventually flowed back to the surface to evaporate, enter the air, and then fall back to the surface as the rain falls back to form a cycle.

This water eventually enters the center of the earth, and only when the earth needs it most does it seep out for human use.

With evaporation, the ecosystem repeats its cycle, returning to land, and from land to sea.

It turns out that if the amount of water on the planet were doubled, the level of the sea brother would rise. The question is how high the sea level has risen, and that's a question. NASA once did a study that drained all the water on Earth, which is equivalent to a water balloon with a diameter of 1,385 kilometers.

We know that the diameter of the Moon is 3400 kilometers, so this water ball is smaller than the Moon. In fact, there are not many reserves of water on Earth, as if the entire ocean has been drained, and there are water balls with a diameter of a thousand kilometers. If the total amount of water were to be doubled into a sphere 2700 km wide, it would not be larger than the Moon.

Much of the Earth's surface will be submerged.

Coastal cities will disappear. Europe will sink completely. Only the traditional highlands, such as the Tibetan Plateau, the mountains of Asia, and the mountains of Europe and the Americas, have survived.

Unlike the melting glaciers, doubling the total amount of water is a huge increase and a more profound change in the land area of the Earth's surface.

70% of the Earth's area is occupied by the ocean, the land area is less than 30% of the Earth's water, the sea occupies more than 90%, 90% of the freshwater resources are frozen in the Arctic and Antarctic, if the Earth's water volume doubles, the sea level will rise by thousands of meters, the Earth will become a water balloon, and only the mountains in the upper part of the high seas will rise to the surface of the water and become islands in the ocean. The biological chain on Earth will break. Because the increase in the mass of the Earth will force the Earth to rotate and the bench to rotate faster, the day on Earth will be less than 24 hours, and the height of icebergs in the Antarctic and Arctic will more than triple.

It literally drains the water from the planet. What do we drink? Remember, 70% of your body is made up of water.

But it is impossible to drain the earth with the pumping tools of man. It's just a matter of time. But to pump water, you first need to find a place to consume water.

The earth, as a relatively independent small carrier in the universe, wants to suck up the water from its body. First of all, we need to consider smoking in **? Pumping seawater into the desert is like stealing a bell.

Eventually, the water flows into the creek and towards the sea.

The number of human beings will be halved and the total amount of water resources will be doubled, proving that the sea level will be in dire straits, and the living space for human beings will be reduced, the environment will be worse, and the surplus human beings will face extinction.

It will lead to the survival of human beings becoming more difficult, the increase in water volume will lead to natural disasters in many areas, and the living environment will become smaller and easy to lead to the extinction of human beings. Thing Kaisen.

There may be some natural disasters, which can easily lead to floods, affecting the survival of human beings, and many places may be submerged, resulting in the problem of imitation panicle pulsation in plant growth.

The advantage is that the desert area will be multiplied and reduced, and human beings will no longer have to be troubled by the lack of water resources. The downside is that the land area will become smaller, and it will be more difficult for humans to survive.

Introduction: In fact, the earth's water resources are very abundant, for example, most of the earth's surface is covered by the ocean, it stands to reason that the earth has 13 billion tons of water, why can human beings only use the water in it?

Because the water that people drink in their daily life is fresh water, and seawater is salty water, the salt content is relatively high, and it takes a lot of money to remove this salt, so most people will not purify seawater. In this case, you can only drink fresh water, but the content of fresh water in the earth is relatively low, and it is easier for people to exploit fresh water on the surface in their daily life, and the content of fresh water on the surface is even lower, only the total water content. Therefore, the water resources available to human beings are relatively small, but the water resources are indeed very abundant.

Therefore, in this case, it is necessary to pay attention to the fact that if you do not have good reserves or cherish fresh water resources, then there will be problems in the use of water resources. And there are some areas where the distribution of water resources is relatively uneven, for example, there are some areas that are very dry and the precipitation is low, but there are some areas where the distribution of water is good, so we must pay attention to the allocation of water resources in daily life.

In fact, water source is very important for people's drinking water, rivers and lakes are the main water source for people in daily life, and the groundwater in the city is also the main water source. If these water sources are damaged by pollution at the source, then it will cause a big crisis. In your daily life, if you want to travel near the reservoir, do not throw garbage into the reservoir and do not throw non-degradable items.

And if there is a river in front of your house, don't put garbage in it. In addition, in daily life, we must pay attention not to exploit groundwater without permission, these groundwater are very precious liquids, so protecting the water source can better promote people's water use.

This is because although the miracle earth has very abundant water resources, only fresh water resources can be used, so only water on the earth can be used.

Because there are 13 billion tons of water on the planet, and a large part of it is glaciers in the Arctic and Antarctic, only the freshwater that can be used is.

This is because most of the water cannot be extracted, some of it is deep underground, and some of it is in dangerous places.

According to the data, there are hundreds of millions of cubic kilometers on the planet we live in, and these water resources exist in many places on the earth in different forms, but among these water resources, only one can be supplied to human use, and the reason is simpleOnly this water resource isFreshwater resourcesThe rest of the non-freshwater resources are not available to humansAnd the cost of desalination is too high for ordinary people to afford, so desalination is only available in countries where freshwater resources are very scarce.

First of all, human beings need water for survival, but human beings can only use freshwater resources, that is, our groundwater, river water, lake water, spring water and precipitation in the sky, etc., and so much water in the ocean is actually salty water resources, salty water resources are not available for human drinking, even if you go to the sea to swim or surf back, you need to wash with fresh water in time, so salty water resources are basically useless for human life, so human beings can use water on the earth, It's just that insignificant.

Secondly, we all learned how to desalinate seawater when we were in junior high school, so many people have to ask, why don't countries use desalination? What we must know is that the equipment for desalination itself is very expensive, and the cost of desalination is too high, so for these countries where there is no shortage of fresh water resources, there is no need to desalinate water resources, and in countries where desalination is necessary, water costs are also very expensive.

Finally, we also need to understand one thing, the earth we live in is not unique to human beings, there are still many organisms in the ocean, if human beings begin to seize the ocean's seawater resources, then it means that the balance of the ocean will be broken, and the lives of marine organisms will also be seriously affected, so in the current situation that this water resource is not very scarce, desalination does not have to be put on the agenda.

That's because the 13 billion tons of water are not suitable for us humans to drink, and we humans have not found a way to drink it, so we can only use it.

The rest is seawater, and there are some other substances in it that cannot be used, and in general, if you want to process it, it will also require a lot of manpower and material resources.

That's because most of the water on the planet is seawater, seawater is not directly edible, and the water we drink now is only fresh water.

Because most of the water resources are from mountains, rivers and oceans, and the diversion of these waters is very large, so the water resources that can be used by human beings are very limited. Because we use freshwater resources.

Because the rest of the water is seawater, the sea water is very salty and cannot be eaten by humans.

At present, the freshwater resources that are relatively easy for human beings to use are mainly river water, freshwater lake water, and shallow groundwater, and the reserves account for about 7/100,000 of the world's total freshwater reserves. According to research, from the point of view of the water cycle, about 9 000 km of freshwater resources are actually used efficiently in the world per year3

Water resources Water resources on Earth are, broadly speaking, the total amount of water in the hydrosphere.

Seawater is brackish water and cannot be used directly, so the water resources commonly referred to mainly refer to freshwater resources on land, such as river water, freshwater lake water, groundwater and glaciers. Freshwater resources on land account for only the total amount of water on Earth, and most of them (nearly 70 percent) are solid glaciers, i.e. mountain glaciers in the polar regions and in the middle and low latitudes, which are difficult to exploit. At present, the freshwater resources that are relatively easy for human beings to use are mainly river water, freshwater lake water, and shallow groundwater, and the reserves account for about 7/100,000 of the world's total freshwater reserves.

According to research, from the point of view of the water cycle, about 9 000 km of freshwater resources are actually used efficiently in the world per year3

Generally speaking, areas with abundant precipitation have abundant water resources; Areas with low precipitation are poor in water resources. It reflects the abundance of water resources in a country or region, and is usually based on the total annual average runoff and per capita share. The total amount of river runoff worldwide is 47,000 km3, with a per capita average of about 9,000 m3

The total amount of river runoff in China is about 2,700 billion m3, and the average per capita share is about 2,400 m3, which is much lower than the per capita share of the world.
