There is no doubt that water is more than just a necessity to sustain life on planet Earth by quenching the thirst of humans, animals and plants, it is the building block of life and without it, our planet would turn into an uninhabitable wasteland.
At the time you estimate United nations About 3.6 billion people, or about half of the planet’s population, live in areas where water may become scarce for at least one month annually. We find that about 790 million people (11% of the world’s population) do not have access to any improved water supply.
These statistics raise an important question: Will the water on Earth dry up? What are the solutions, and what would the world look like if the oceans dried up?
The five sins behind the causes of water shortage
There are many reasons that will make us face a global water crisis in the future that is worse than the one we are currently experiencing. World Resources Institute Among these reasons:
Climate change is warming the planet, making geographic regions of the world hotter and more scorching and evaporating water.
At the same time, clouds are moving away from the equator towards the poles, due to a phenomenon driven by climate change calledHadley cell dilationWhich deprives tropical regions such as Africa, sub-Saharan Africa, the Middle East and Central America of rain water.
Ironically, climate change is also leading to increased rainfall in other regions, and people who live near rivers and streams are the most likely to be affected, as at present at least 21 million people around the world are at risk of river floods every year. That number would rise to 54 million by year 2030.
All the countries most exposed to river floods are the least developed or developing countries – making them more vulnerable to climate change and natural disasters.
More people + more money = more demand for water. It’s a simple equation. As the population increases and the income increases, the demand for water increases.
The world population, which now stands at 7.5 billion, is expected to increase by 2.3 billion new people by 2050, so how can the planet satisfy their thirst?
Depletion of groundwater begins
About 30% of the fresh water on Earth is found in the aquifer, and people extract it daily for agriculture or use in other fields, and this water is often extracted without proper rationalization.
India is considered one of the countries most threatened by the loss of groundwater, as 54 of its wells are declining, and if consumption continues as it is now, India will live in a critical state within the next 60 years.
There is no doubt that extracting groundwater is not everything, there is also a process of transporting, treating and emptying, and since the infrastructure for transporting water is poor, we lose a large number during this journey.
In the United States alone, 6 billion gallons of treated water are lost every day from leaking pipes.
Wrong price for water
Globally, water prices are far below its real value, as its price does not reflect the true total cost of the service from transportation through infrastructure to treatment and disposal, and this has led to misallocation of water, lack of investment in infrastructure and new water technologies that use water. More efficiently.
For example, why would a company or government invest in expensive water saving technologies when the water is cheaper than the technology in question?
But when the price of getting clean water is closer to the cost of actual service, people will be incentivized to use the water efficiently.
Will the water dry up from the planet?
In its latest annual report on the biggest global risks, he is included World Economic Forum The persistence of “water crises” is among the most important threats facing the world, preceded by other issues such as terrorist attacks, food safety and financial crises.
Water is a vital resource for our homes, industrial production, food production and ecosystems, but water consumption in the world is increasing dramatically, and in many places, getting enough water is a major challenge, and if the great waste of water that is happening now continues, the answer is yes, water can To be dry from a cup of earth.
Some major cities in the world, such as Cape Town in South Africa and Chennai in India, talked about “Day Zero” as the day when it will not rain and there will be no water in the taps, and the reason is the emptying of aquifers in the foreseeable future if the current unsustainable pumping of water continues. According to the website Sciencenordic.
Solutions to get rid of the water crisis
Here is a look at the things that experts say are needed solutions in order to get rid of the water crisis, according to the site Circle Of Blue.
Education to change consumption and lifestyles
Dealing with the coming era of water scarcity requires comprehensive reforms for all forms of consumption, from individual use to the supply chains of large corporations, as well as educating people about the importance of water conservation and the damage that diminishing will cause.
Some regions, such as India, Australia and the southwestern United States, are already facing a freshwater crisis.
Innovating new technologies to conserve water
In areas where aquifers dry up and rainwater is more difficult to predict, so innovation is needed.
Participants in World Water Day are always urged to adopt a new mindset for wastewater treatment.
Some countries, such as Singapore, are trying to recycle to reduce water imports and achieve self-sufficiency.
Improving irrigation and farming practices
In some cases, excessive irrigation practices weaken farmers’ ability to provide food and fiber to a growing world, and remember that about 70% of the world’s freshwater is used for agriculture, so improving irrigation can help bridge supply and demand gaps.
Consumers have always questioned the utility of water prices, but according to OECD experts, raising prices would help reduce waste and pollution.
Developing and implementing better policies and regulations
With water scarcity complicating food security and pollution, governments of countries around the world need to redefine their role in order to ensure more water protection.
There is no doubt that poor infrastructure leads to the destruction of health and the economy, as it wastes water resources, increases costs, reduces its quality, and allows preventable water-borne diseases to spread among vulnerable populations, especially children.
Climate change mitigation
Climate change and water scarcity go hand in hand to create one of the greatest contemporary challenges to humankind.
These are interrelated issues identified by the Intergovernmental Panel on Climate Change in which water management policies and measures can have an impact on greenhouse gas emissions.
While pursuing renewable energy options, the water consumption of these mitigation methods must be taken into account when producing alternatives ranging from bioenergy crops to hydropower and solar power plants.
Control over population growth
Due to the accelerating growth in the world’s population, parts of the world could witness a gap between supply and demand of up to 65% in water resources by 2030, and currently more than a billion people do not have access to clean water.
With 70% of the world’s freshwater used for agriculture, the vital role of water in food production must be considered with changing climate and resource conditions.
What would the Earth look like if the oceans dried out?
At least it won’t happen soon, but it is likely to happen, if not in your life then it might be in the life of your grandchildren.
In 2008, Horace Mitchell of NASA created a video in which he revealed what the Earth would look like if the ocean water evaporated.
But in 2020 Dr. James O’Donogo, a planetary scientist at the Japan Aerospace Exploration Agency, prepared a new version of the old video but with higher resolution and slower animation to better see the effects.
The new video also clearly reveals what the term “sea level decline” means, and all these details are taken from the NASA observatory.
Finally, we must not forget that Mars was once a wetter and warmer place than it is today, especially since theories say that a third of Mars was covered by an ocean, and the evidence is found in the chemical composition of the Martian soil, as well as in some features that are similar to the features of beaches The floor.
