What Would Happen If It Didn’t Rain For A 100 Years? – Effects on Earth Due To Lack Of Rainfall: – American scientists say that if billions of drops from 0.5 mm to 7 mm in size, which form rain, stop falling from the sky, this could trigger a global catastrophe. If precipitation stops, one of the most global processes occurring in nature, namely the constant circulation of water, will be disturbed.
First, all plants will disappear, many of which serve as food for people and animals. Then some species of animals will die out, followed by predators that feed on herbivores. The composition of the atmosphere will also change and the temperature will increase.
All these factors can provoke the death of mankind because people without water can live no more than three days.
Let’s see some important impacts due to lack of rain:
What Would Happen If It Didn’t Rain For A 100 Years? – Impacts on Earth Due To Lack Of Rain
1. Lack of fresh drinking water:
If there is no precipitation, then the world’s freshwater resources will be very scarce. But the freshwater resources on the earth are probably only 3% of the water content on the earth. Not only that, but 3% of the freshwater resources and 68.8% are some frozen glaciers.
Without precipitation, the temperature on Earth will continue to rise, and these glaciers will also melt into freshwater. But there are so many people in the world with more than 7 billion people. These freshwaters will not last long.
Then the humans in the world will begin to dilute the sea, but although there are many seawaters, they can only be dried up in a few hundred years. It will also be accompanied by a large number of marine life deaths, but this is only the beginning.
Because it will not take long, many plants on the land will die in large numbers. And the entire food chain will slowly collapse when the plants at the grassroots level die.
The drought is an anomaly climatological transient in which the availability of water is below than usual in a geographic area. The water is not enough to supply the needs of the plants, the animals and humans who live in this place. The main cause of any drought is the lack of rainfall or no rainfall, this phenomenon is called meteorological drought.
And if it persists, it results in a hydrological drought characterized by the inequality between the natural availability of water and the natural demands of water. In extreme cases, aridity can be reached. Drought periods can have important consequences for the environment, agriculture, the economy, health, and society.
The effects vary depending on the vulnerability. For example, subsistence farmers are more likely to migrate during a drought, since they have no alternative food sources. Areas with populations that depend on subsistence agriculture as the main source of food are more vulnerable to famine.
The most common consequences of drought include:
• The decrease in agricultural production and livestock carrying capacity.
• Malnutrition, dehydration and related diseases.
• Famine due to loss of food crops.
• Mass migration, resulting in a large number of internally displaced persons and refugees.
• Damage to the habitat, affecting wildlife in the terrestrial and aquatic ecoregion.
• Dust storms, when a drought affects an area that suffers from desertification and erosion
• Social unrest, conflicts, and wars over natural resources, including water and food.
• Discontinuation of food sales in the market
3. Our Earth may turn to second Mars:
Even if the food chain does not collapse, the concentration of carbon dioxide on Earth will rise sharply when a large number of plants die. Because most of the creatures on Earth need to breathe, there will be carbon dioxide in their breathing.
Without plants to convert carbon dioxide into oxygen, the oxygen on Earth will soon be depleted. At the same time as consumption, the global temperature will rise further. Because the atmosphere is very thin under the action of carbon dioxide.
The light and heat of the sun can be transmitted to the earth more completely. Then our earth may become a deserted planet filled with yellow sand under the sun’s roasting, just like the Mars in our solar system. By then our planet became the second “Mars” in the solar system. But before this, we humans may have already immigrated.
4. Most expensive electricity:
The hydroelectricity is comparatively cheaper than the electricity produced from other sources. Because the plants are already amortized, water is free and require little employment. This energy source contributes to lower the price of electricity, but if there is no water, the price goes up.
Because then the electricity has to be produced with the most expensive energy: coal and gas. Of course, promoting other sources of renewable electricity would also make it possible to lower the electricity bill. As it is well known that wind and solar energy are cheaper than coal, gas or nuclear.
In the long term, they also save millions in healthcare expenses. Therefore, promoting self-consumption with a Net Balance is also very beneficial for society. One of the many advantages of solar and wind energy is that they do not require water for operation. Nuclear, coal and gas plants require water in large quantities.
For example, a 1,000 MW nuclear power plant requires up to 20,000 million liters of water per year.
5. More expensive water and food restrictions:
When it doesn’t rain, the water cost not only increase but we can find water restrictions that mainly affect villages, which must be supplied with tankers. Also, obviously, water is restricted to clean streets, water gardens, fill pools.
Before cutting the water in the cities, the water in agriculture is reduced, which leads us to lower agricultural production and the rise in prices of the most basic products.
6. More pollution and more hospital expenditure:
The greatest air pollution when it does not rain is mainly due to two reasons: more electricity is used from polluting sources. And, when it does not rain, the air in the cities is not cleaned. Do not forget that when it rains the air is cleaned but the water of rivers and seas gets dirty.
Because the pollution does not disappear but instead changes place. The increase in air pollution has consequences, such as Restriction of car driving in some cities and speed reduction on certain roads. Impairment of public health and increased visits in-hospital emergencies. Increase in premature deaths due to pollution.
7. Biodiversity more threatened:
If there is no water, wetlands could dry out, affecting fish, amphibians, birds … including many threatened species. The desertification is fed with less rain and when forests are drier are more prone to fires.
And burn better when unconscious, uncultured or insensitive people set fire to the mountain. Drought affects wildlife very negatively: animals find less food, are more vulnerable to disease and die more naturally.
8. International conflicts:
Depending on the affected region, drought can cause mass migration and violence to control available resources. This is another argument to try to reduce global warming. The 1967 Arab-Israeli war was largely tied to the growing need for water in the Middle East.
The question is still relevant. The Jordan River is controlled by Israel; in dry periods, Israel restricts water supplies to the Palestinians. During the hot summer of 2016, about 2.8 million Arab residents of the West Bank and local leaders repeatedly complained about the denial of access to fresh water.
Israel blames the Palestinians for not wanting to sit down to negotiate to decide how to upgrade their outdated infrastructure. Jordan River which flows through Lebanon, Syria, Israel, the West Bank, and Jordan, is at the center of one of several permanent water-related interstate conflicts. It has been a source of tension between Israel and the Arab states for over 60 years.
Many conflicts between Pakistan and India have arisen because of the use of the waters of the Indus River, which flows through their territory. In Africa, armed clashes due to water supplies are not uncommon. Botswana, Angola, and Namibia cannot divide the Okavango River delta. The world’s longest river Nile is the point of disagreement between Ethiopia, Sudan, and Egypt.
Egypt fears that the White Nile will dry up, flowing through the territory of Sudan and Uganda. Not reaching the Sinai desert, and Ethiopia claims to extract most of the water from the more full-flowing Blue Nile, which is disadvantageous for Egypt. It is believed that the fall of the Gaddafi regime in Libya was due to the fact that large stocks of drinking water are concentrated in the Libyan Jamahiriya.
Gaddafi wanted to implement a water project that could improve the water situation in North Africa. But during the launch of the water project, intervention in Libya began.
After the overthrow of Gaddafi in Libya, the water issue was not raised. It’s not hard to think about what will happen in the world if there is no rainfall at all. The world will go through war and many nations may lose their existence.
9. Lack of rain multiplies viruses:
In the absence of rain, the accumulation of aerosol particles in the atmosphere increases. These viruses and aerosol particles, being in higher concentrations, can have important health effects.
In fact, recent studies have found a direct relationship between pollution levels, more intense due to the lack of rain and winds, with increased consultations for respiratory diseases and allergies. High temperatures have increased allergy levels and the anticyclone situation prevents the spread of contamination.
10. The winter harvest will be in danger:
Absence of rainfall will cause many fields and farmland to significantly reduce their harvest, with cereal crops being especially vulnerable. Other agrarian sectors such as pastures, extensive agriculture, or fruit trees such as almond or olive trees will also be at risk. They are winter crops that can lose much of their harvest. The fields and cultivation will be significantly reduced.
11. Increase fire risk:
One of the driest winters of recent years will also leave consequences for the fire season. At the gates of spring, the rainfall deficit will increase the risk of fire. Experts say that anthropogenic warming will increase the extent of the area burned by fires in Mediterranean Europe.
12. Oxygen level reduces:
Human drinking water can only use seawater desalination technology on a large scale, extract fresh water from the ocean. And transport icebergs from the Antarctic Arctic to supplement the freshwater needed by the human body.
But humans will return to the primitive social state and have a large-scale war for water. As the vegetation on the earth gradually decreases, the amount of oxygen formed by photosynthesis will be less and less. A large number of living things on Earth will gradually become extinct due to lack of oxygen.
13. The disappearance of plants:
Plants that rely heavily on water die within a week, and drought-resistant plants may last for weeks. For vegetables and crops, people can only irrigate by distilling seawater. But this water resource is limited, and if there’s no rain it can disappear completely within 2500 years.
When the plants are dead, the food chain naturally breaks. No creature can survive. Second, the disappearance of plants can lead to dramatic changes in the Earth’s atmosphere. No plant photosynthesis means no oxygen, and oxygen on Earth can only last for more than 2,000 years.
Without the protection of plants, the temperature on the earth will rise rapidly, the surface will become desert, and it is difficult for human beings to survive.
14. Adverse effect on health:
Lack of rain and subsequent air pollution, indoors or outdoors, aggravate respiratory diseases, asthma, and allergies. But also the decrease in available water and its variations in quality, including the increase in its temperature, is related to the occurrence or increase of vector-borne diseases and infectious diseases transmitted by water and food.
The dry environment can also prove fatal to the skin. In fact, air pollution decreases the ozone layer. And this increases the incidence of ultraviolet radiation at the surface of the earth, which determines the increase in the rates of skin diseases, including cancer and ophthalmological lesions.
Also, things can be complicated at an epidemiological level, facilitating the spread of viruses, as one of the most familiar at this time of year, the flu. It is an acute viral infection that is easily transmitted from one person to another.
Their viruses circulate throughout the world and can affect anyone of any age. Emergency water stations are an essential part of workplace safety for many laboratories and factories. A steady supply of water is required in the event of harmful chemical exposure.
Many Occupational Health and Safety requirements suggest that all emergency showers should be able to pump 75 liters per minute for a minimum of 15 minutes. No rain means no water which results in occupational health risks.
15. The critical condition for sewage disposal:
Another aspect is that part of the river and ocean water is used for domestic supply in the region’s cities and also receives sewage. When the rivers are full, the sewage is partly diluted. But when the water volume drops to only 10% of the original, the effluent concentration increases and the treatment process becomes more expensive.
The situation is becoming worrying as the press reports news of a technology – funded by Bill Gates – that extracts water from feces. Just think the critical situation has arisen already and what will happen if there is no rain at all. We will be forced to drink water that has been extracted from the feces and urine.
16. The beverage market will however grow:
Not surprisingly, over the past two decades, bottled water has become the fastest-growing beverage market in the world. In 2013, its volume was estimated at 157 billion dollars. By 2020, the market is expected to almost double, to 280 billion.
Compared to 1980, water sales in the world increased one hundredfold. Nevertheless, in the past five years, the volume of bottled water production in the market has been steadily increasing. Both fears of being infected by tap water and the market activity of manufacturing companies are affecting.
So obviously when there’s no rain, there will be no fresh water. The industries that have been supplying bottled water will be gaining huge business since each person will be forced to buy the bottled water for drinking. So the industry will grow fast pocketing millions of dollars since the production of such drinkable water will cost more if there is no rainfall at all.
Scientists say that if there is no rain on the earth for a hundred years, humans will focus on salvage irrigation of crop vegetables to ensure adequate food. Because the rivers and lakes are dry for a long time without rain, human drinking water can only use seawater desalination technology on a large scale.
From the perspective of ocean extraction, all the hydropower plants will stop running, thermal power generation, and nuclear power plants are also in jeopardy. On land, in the Antarctic, the Arctic glaciers melt, the sea level rises and submerges the land, and then the Earth’s temperature drops sharply, and the whole earth will be frozen.
However, a situation like this may not come for.many more years to come. Still, the water cycle is going on, the rain will timely fall. But looking at the global warming effects, we must fear for the situation.
Opponents of the water crisis claim that the water on Earth will not disappear, referring to the water cycle in nature. Freshwater is a renewable natural resource. Water evaporates, then condenses, falls on the Earth in the form of rain, snow and other sediments that seep into the soil, into rivers, seas, and oceans.
The process of the water cycle in nature is eternal. Therefore, the complete disappearance of freshwater to humanity is not threatened. There is enough water on the planet, but it is mostly salty, and desalination is very expensive. Freshwater on Earth is enough, but it is unevenly distributed.
In some countries it is in abundance, in others it is deficient, therefore water conflicts arise. The main problems are not water shortage on Earth, but water pollution, lack of funds for its production ( groundwater ), expensive desalination of saline water.
