Will we ever run out of water?
While our planet as a whole may never run out of water, it's important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world's freshwater can be found in only six countries. More than a billion people live without enough safe, clean water.
Unless water use is drastically reduced, severe water shortage will affect the entire planet by 2040. "There will be no water by 2040 if we keep doing what we're doing today". - Professor Benjamin Sovacool, Aarhus University, Denmark.
In reality, the world won't run out of water. Water does not leave Earth, nor does it come from space. The amount of water the world has is the same amount of water we've always had. However, we could run out of usable water, or at least see a drop to very low reserves.
Assuming a World average water consumption for food of 1,300 m3/year per capita in 2000, 1,400 m3/year in 2050, and 1,500 m3/year in 2100, a volume of water of around 8,200 km3/year was needed in 2000, 13,000 km3/year will be needed in 2050, and 16,500 km3/year in 2100. Will that much water be available on earth?
A full 16 years ago, in 2001, the UN Population Fund warned that the world will begin to run out of fresh water by 2050, and UNFPA's World Population Report from 1992 also warns of water shortages by 2050.
How bad could it be? According to current projections, Cape Town will run out of water in a matter of months. This coastal paradise of 4 million on the southern tip of South Africa is to become the first modern major city in the world to completely run dry.
According to Professor Cribb, shortages of water, land, and energy combined with the increased demand from population and economic growth, will create a global food shortage around 2050.
Yes, it is possible to make water. Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.

Water Facts - Worldwide Water Supply.
Rapid population growth, climate change, high demand for food, manufacturing, and the economic crisis have left the world in dire shortage of a number of critical things. Some of these, like water, soil, and antibiotics, are things we can't live out.
Will there be water wars?
Violent clashes over scarce resources have been predicted as “likely,” or even “certain” for 35 years, and despite such “water wars” never having happened, hypotheses about them keep cropping up around conflict-affected regions such as the Middle East and South Asia.
Humans cannot drink saline water, but, saline water can be made into freshwater, for which there are many uses. The process is called "desalination", and it is being used more and more around the world to provide people with needed freshwater.
Our Sun is middle-aged, with about five billion years left in its lifespan. However, it's expected to go through some changes as it gets older, as we all do — and these changes will affect our planet.

The Hydrological Cycle: Water Is Neither Created Nor Destroyed, It Is Merely Transformed. The title of this article paraphrases the famous sentence of French chemist Antoine Lavoisier in his “Law of Conservation of Mass.” He sustained that mass is neither created nor destroyed in chemical reactions.
Desalination is the process of removing salt from seawater, making it drinkable. This is done either by boiling the water and collecting the vapor (thermal) or by pushing it through special filters (membrane).
1. Eritrea: 80.7% lack basic water services. The population of Eritrea in East Africa has the least access to clean water close to home. Lack of adequate household sanitation means open water sources are often contaminated by human and animal waste.
The water on our Earth today is the same water that's been here for nearly 5 billion years. So far, we haven't managed to create any new water, and just a tiny fraction of our water has managed to escape out into space. The only thing that changes is the form that water takes as it travels through the water cycle.
From lab-grown meat, edible insects, seaweed, a stronger shift towards plant-based foods, to massive changes in food production and agriculture, the next decades will see a considerable shift in what food we put on our plates.

Will food prices go down in 2023?
As for 2023, this is the first outlook for food price inflation for the coming year. In 2023, food-at-home prices are forecast to rise between 2.0% and 3% with food-away-from-home prices predicted to increase between 3% and 4%. Overall food price inflation is forecast up from 2.5% to 3.5%.

Drinking seawater can be deadly to humans.
When humans drink seawater, their cells are thus taking in water and salt. While humans can safely ingest small amounts of salt, the salt content in seawater is much higher than what can be processed by the human body.

California
About 46% of the state experienced exceptional drought conditions, the worst possible drought level and by far the highest such share nationwide.
How long before California runs out of water?
The National Aeronautics and Space Administration (NASA) is now predicting that California only has enough water supply to last one year.
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
By 2050 , the world's population will exceed at least 9 billion and by 2050 the population of India will exceed that of China. By 2050, about 75% of the world population will be living in cities. Then there will be buildings touching the sky and cities will be settled from the ground up.
