Question

What will happen if the total supply of potable water is finished?

Answer 1

Hint: The term potable means safe to drink and drinkable. Water is essential for living organisms. No living organism can live without water. But all water present on earth is not drinkable. Water may contain many microbes and chemicals which make them unsuitable for drinking. There are certain parameters set for the drinking water quality, by the state or country based on WHO guidelines.

Complete answer:
Life on the earth will come to an end, (except for some sea creatures) if the total supply of potable water is finished.
Water is essential for all living beings to work and function properly. All the reactions occurring inside cells (metabolic reaction) need water to proceed.
We can estimate the importance of water in animals by knowing the fact that our bodies constitute more than or about 60 percent of water.
The underground water or water from ponds and rivers are made potable by different processes before supplying to our houses.
Lack of water in our body will impact other bodily functions. Without sufficient water intake:
Your body temperature won’t stay regulated.
Your electrolytes will be unbalanced and you will get dehydrated.
Your joints may not work properly.
Your brain may swell.
Your blood pressure may increase or decrease.
Lack of potable water on earth will affect the body system slowly. Body at the initial stage of inadequate water supply will try to meet its requirements by burning the stored starch. After a little time, the body starts to eat fats and meet its requirements. And if this situation prevails the body ultimately starts to digest the protein which ultimately leads to the death of an organism.

Note:
The parameter which determines the quality of drinking water includes color, pH, odour, taste, hardness of water and other chemicals present in it.
Seawater can be made potable by reverse osmosis technique or by the steam distillation process.
If we will not be able to produce potable water from sea water in time all life on earth will come to an end.
