Why has water become the source of life?

Greek philosopher Thales said, “Water is the source of all things, and everything begins with water and returns to water.” Whether past or present, it is clear that we cannot survive without water. So why did our bodies decide to use water molecules out of all the substances on this planet? Why can't life survive without water? 

Natural ice has a six-claw shaped hexagonal reflective structure, which is the most stable structure in nature, and this structure is made up of one oxygen atom and two hydrogen atoms.

Also, water molecules form covalent bonds to form a curved (104.5°) structure. The structure of these water molecules plays an important role in its properties. This structure has the unique characteristic of forming a hexagonal structure as it turns into ice, allowing marine life to form an ice layer from above as they spend the winter. Water also has a high specific heat, which is important for regulating body temperature. Because water is polar, it also acts as a solvent within living organisms. And it can circulate nutrients by transporting nutrients and waste products within water and organisms. Water is highly cohesive, meaning water molecules are weakly bound to each other, allowing even tall trees to transport water from roots to branches and leaves, providing water to all cells.

Water makes up approximately 70% of the human body and has a significant impact on physiological aspects. It promotes metabolic processes. Water makes up the blood and lymph, transporting nutrients and oxygen. It also acts as a catalyst in chemical reactions, especially important in hydrolysis. Hydrolysis involves breaking down compounds, including proteins, carbohydrates, and fats, by adding water molecules. For example, in the human gastrointestinal tract, digestion of food through the amylase enzyme is a hydrolytic process. This means that without water, digestion cannot occur and nutrients and energy cannot be obtained. Water not only directly affects living organisms, but also affects our living environment. A representative example of an environmental aspect is the water purification process. 

Known as natural purification, water undergoes a self-cleaning process. According to the Chongjin City Waterworks Department, midnight includes dilution of pollutants by large amounts of water, precipitation of pollutants, decomposition of pollutants by sunlight, and oxidation or neutralization by reaction with oxygen.

Biological self-purification also occurs when algae or aquatic plants utilize pollutants as nutrients to reduce pollution levels. Water is therefore essential to our lives, and it is essential for reasons that may seem obvious. However, many patients ignore this fact and endanger their health. Therefore, we must maintain healthy eating habits by developing the habit of consistently consuming water.
