6 facts that make you change the way you think about using water

According to experts, if the country continues to waste water, Earth will "die thirst" in 2030.

The facts make you change the way you think about using water

Speaking of water refers to the first element that determines life. Because water is an indispensable thing in human life, we can fast for a few dozen days but cannot keep drinking for more than 10 days.

Although the country accounts for three-quarters of the Earth's area, only about 2.5% of the total water is usable.

The summary of Business Insider page below will provide you with amazing facts about water - an extremely familiar element in our lives.

1. We are consuming too much water in the agricultural sector

Hydrologist - Tess Russo, after estimating the amount of water available worldwide, said that only 10% of farmers are aware of the amount of water their land plots really need, the rest seems to not care much. It is this that leads to a great waste of water in agriculture.

More alarming, the 80% figure Tess gave is only average. The truth is that in a dry year, California farmers can use up to 90% of the state's water. But drought is not just a problem of the state of California, it's a problem of the whole world.

Heidi Hammel - foreign space researcher said, even if you say that California is really a great farm - where more than half of vegetables and fruits are grown in the US but in fact, many other areas cultivate fruits and seeds . to supply the world. If water is wasted everywhere, not much will Earth run out of water.

2. Water pumping activities can cause earthquakes, landslides and collapsing pits

In fact , excessive exploitation of water and the discharge of " bluff " wastewater into the environment have made the structure of the Earth's crust - which is only composed of debris such as silicate and mantle - become porous and weak. go.

According to experts, this leads to an inevitable consequence of accidents such as death lodges , heavier than landslides and even earthquakes.

3. 6.85% of water on the international space station is recycled from waste water

We all know, transporting food and drinks to the space station is extremely difficult and time-consuming. Usually every year there are only 2 - 3 supplies to be transferred to the space station, so everything here must be saved to the maximum, especially water.

Most of the water on the space station comes from the astronauts, sweat and urine. NASA installed a urine recycling machine in 2008 to save about 2,800 liters annually when the ship entered Earth's low orbit.

This is said to be extremely important because we are considering bringing people to Mars . At that time, we will need to increase water reuse capacity to 95%. Because, it will be very difficult for us to bring water into space, and the other part is because Mars has no atmosphere to condense or the appearance of rain.

4. If the Earth runs out of water, we can go to Mars to get water

So far, many scientists believe that Mars is a dry planet. But a new study shows that Mars shells contain water at the same rate, even larger, than the Earth's crust.

Dr. Francis McCubbin and Dr. Erik Hauri of the Carnegie Institution (USA) and his colleagues analyzed two samples of Martian meteorites dating back about 2.5 million years ago.

The analysis shows that water accounts for 70 to 300 parts per million in the Martian shell. Meanwhile, the ratio of water in the Earth's crust is between 50 and 300 parts per million . This indicates that water exists in Mars's formation and that the planet has the ability to hold water below its surface.

Further research, experts say, if you dig about 1 km deep, you can meet water on Mars, but the problem is, how can you drill down to that location to find water.

5. Lack of water, people once intended to 'pull' water from the polar regions to use

In the 1970s, a Saudi prince rekindled a global tape-pulling company with the intention of pulling a block of Antarctic ice into Mecca and melting it into fresh water to serve the people. during pilgrim season.

It is estimated that the cost of pulling 100 million tons of ice to Mecca will fall to about 100 million USD (about 2,100 billion VND at the current exchange rate) and the trip will take about eight months.

But after debating this program during an international conference in Iowa and testing in San Francisco Bay with a huge block of ice, the operator of the company determined the plan would not succeed. Eventually, the company gradually disintegrated in the late 1970s.

6. Predict, Earth will "die thirst" in 2030

UN statistics show that every 15 seconds in the world there is a death in children due to related diseases lacking clean water and hygienic conditions.

Every day in the world, up to 4,000 children die from diarrheal diseases that are mainly caused by unsecured hygiene. Every year, millions of people around the world need to be supplied with clean water and minimum sanitary conditions at a cost of up to ten billion dollars.

At the same time, it is estimated that an average of 40% of the world's population is currently living in a shortage of clean water for living, especially in Africa.

Therefore, if not saving and using water appropriately, the researchers predicted that the Earth will be in serious shortage of water by 2030.
