How important is water for life on planet Earth?
The Earth is unique among all the planets of the solar system in possessing water in all three states; solid, liquid, and gaseous, according to what science has reached so far, as water covers about 75% of the land area, and in its three states it is found in the layers of the atmosphere so that it is formed in the troposphere, through which it moves to the stratosphere, and water is of great importance When it comes to the life of living organisms, it is considered a necessary part to complete the most important physiological biological processes in their bodies. Such as nourishment and digestion from waste produced inside cells, for example, plants get rid of excess water by throwing it as moisture on their leaves.
Water contributes to the creation of biological diversity in the place in which it is located, as any change in the quality of water leads to a change in the numbers and types of living things around it, for example, places where water collects, such as streams, lakes, and wetlands such as swamps are sensitive points for ease The arrival of sediments and other pollutants to it or to places close to it, causing a change in the quality of the water in it and thus disturbing the environmental systems.
A humid environment is an ideal natural environment for living organisms to live in. Such as plants, animals, and birds, and these environments also contribute to the creation of commercial and recreational activities in the region that provide employment opportunities for many, and water plays a major role in shaping the topography of the earth’s surface, such as canyons, plains, and places where water collects as a result of floods. Water is unique to many of the properties that different organisms need, by entering into chemical processes and reactions inside their bodies, in addition to preserving the shape of the basic components of their cells.
How important water is in all aspects of human life
The importance of water in a person’s life is not limited to its use for drinking, but there are many other aspects in which water is indispensable, as it is used in the following:
- Cooking and food preparation.
- Personal hygiene and bathing.
- Daily use, such as washing clothes, utensils, and dishes.
- Irrigation of plants and agricultural crops, parks, and gardens.
- Cleaning homes and compounds.
- Manufacture of some products.
- Entertainment; Such as pools and swimming pools.
Factors affecting human water needs
The human body depends mainly on water, which is the main chemical component of the body, and there are several factors that are relied upon to determine the most appropriate amount of water for a person, where these factors can be summarized as follows:
- Sports activity: When practicing any physical activity, the body sweats to maintain its moisture and temperature and thus needs an increase in the amount of water, and this can be achieved by drinking water before and after exercise, or drinking sports drinks containing several minerals and elements needed by the body. The surrounding environment: the rate of the human body’s need for water increases with the increase in temperature and the rate of humidity in the surrounding environment, as well as at high altitudes, so it is necessary to pay attention to the need to increase the amount of water consumed on hot or humid days, even if exercise is not done at the time…
- Body health: When the body is exposed to a health condition that causes fever, diarrhea, or other conditions that may cause loss of body fluids, the body’s need for water increases to compensate for what was lost, and the need to drink additional quantities of water in the event of chronic diseases increases. Diabetes, heart disease, inflammatory diseases, bladder, and urinary tract stones, and periods of pregnancy and breastfeeding cannot be overlooked either, during which a woman’s need for water increases.
- Travel: moving from one climate to another during travel leads to sweating and loss of fluids, and thus the need for more quantities of water to compensate for that loss. Therefore, it is imperative to make sure to drink water at all times while traveling.
