Water is the basis of all life on planet Earth. It occupies 2/3 of the surface of the entire planet, participates in many processes and reactions. It is not for nothing that water is called the source of life.
Instructions
Step 1
Water exists in three states: liquid, gaseous (in the form of fog) and even solid (ice). It is an excellent solvent for many substances and chemical elements. Rivers, seas and oceans account for about 97% of all water on the planet. The rest of the percentage circulates in the form of mists or is in a frozen state.
Step 2
A person simply cannot exist without water, because he consists of 70% of it. Blood, brain, bones contain this compound. If the loss of fluid by the body is about 5-8%, then this can lead to severe dehydration, loss of consciousness. If a person loses more than 12% of the water, then death occurs.
Step 3
All vital functions of the human body, and of other mammals, take place in a liquid medium. It is with the help of the liquid that the work of the immune system, the endocrine glands and the excretory system is maintained, and the body temperature is regulated. It is due to the high water content that the blood is able to dissolve various useful substances and transport them to cells and organs.
Step 4
For normal functioning, a person needs to consume about 1.5-2 liters of liquid per day. It can be simple drinking water, soups, even solid foods are 50% of this element. Doctors recommend drinking more liquid in the morning in the hot season in order to create some reserve, and in the heat itself, limit its intake. Then the loss of moisture will be significantly reduced, and dehydration will not occur.
Step 5
But not only man needs water for life. All life on Earth needs moisture. Plants with their roots absorb water and minerals dissolved in it from the soil. Without this, their growth and development will simply be impossible. Even cacti store liquid in their fleshy leaves and body.
Step 6
Water is the habitat of many animals, fish, insects. Since it is capable of dissolving oxygen in itself, it becomes an ideal environment for the normal life of various organisms.
Step 7
Having destroyed and polluted the supply of water suitable for drinking and the life of organisms, humanity will cease to exist. For fresh water to be enough for all living things for many centuries, everyone needs to think about ecology. Do not simply waste tap water, constantly check the plumbing, pipes, so that not a single drop of life-giving moisture is wasted.
