Annotation:
Water circulates nutrients in nature and is a habitat for numerous species of plants
and animals. Understanding the role of water in nature and in human life is becoming especially
relevant in the context of modern environmental problems associated with a shortage of clean
fresh water. The article highlights the important role of water in nature and in human life.
Keywords:
a living organism, biochemical processes, balance in ecosystems, the role of water in
nature and in human life, environmental problems, fresh water.
Water is one of the most important substances on planet Earth. No living organism can exist
without water. It is the basis of biochemical processes, regulates climatic conditions, shapes
landscapes and maintains balance in ecosystems.
Water occupies about 71% of the Earth's surface, but only 2.5% of all water is fresh and
drinkable. All living organisms depend on water to one degree or another: plants use it for
photosynthesis, animals use it to support the vital functions of the div.
Water circulates nutrients in nature and is a habitat for numerous species of plants and animals.
Seas, rivers, lakes and swamps are important elements of the biosphere, on the condition of
which the diversity of life on the planet depends.
An important feature of water is its unique ability to maintain a temperature balance in
ecosystems. Due to its high heat capacity, water softens temperature fluctuations, creating
favorable conditions for life [1].
The water cycle is a global process of water movement between the oceans, atmosphere and land.
This process includes evaporation of water from the surface of the seas and oceans, condensation
of moisture in the atmosphere, precipitation and the return of water back to reservoirs through
rivers and groundwater [3].
The water cycle ensures the constant renewal of fresh water reserves on the planet, regulates the
climate and maintains soil fertility.There is no single "reservoir" for water on Earth; it is
constantly moving and redistributing, creating a dynamic system.
The human div consists of about 60-70% of water [2]. Water is a part of blood, lymph, and
intercellular fluid, participates in metabolic processes, delivers nutrients to cells and removes
waste products.
Without water, a person cannot survive for more than three to five days. Lack of water in the
div leads to dehydration, disruption of internal organs and, in severe cases, death.
Water also plays an important role in thermoregulation. The daily water requirement of an
adult is on average 2-2.5 liters [5], and all sources of water intake are taken into account:
drinking, food, and metabolic water (formed during the oxidation of fats, proteins, and
carbohydrates).
Water in agriculture and industry
Agriculture is the largest consumer of fresh water: it accounts for about 70% of global water
consumption [6].Water is needed for irrigation of fields, livestock maintenance, and processing
of agricultural products. Industry also consumes significant amounts of water. For example, it

takes about 300 liters of water to produce one kilogram of steel [7].Lack of water resources can
significantly reduce crop yields, lead to higher food prices and disrupt economic stability in the
regions.
Today, about 2 billion people in the world are experiencing a shortage of clean drinking water.
The reasons for the shortage include climate change, population growth, pollution of water
bodies, and inefficient use of resources. In some regions (for example, in Africa and the Middle
East), water scarcity leads to serious humanitarian crises, forced migration of the population, and
exacerbation of conflicts over access to water sources.
Large cities also face water supply problems due to depletion of groundwater aquifers and
surface water pollution.
Ways to solve the problem of water scarcity
Solving the problem of water scarcity requires an integrated approach at the global and local
levels. The main areas of action include:
- Development of seawater desalination technologies.Modern methods, such as reverse osmosis,
make it possible to obtain fresh water from seawater;
- Rational use of water resources.This includes the use of drip irrigation in agriculture, the use of
water-saving technologies in industry and everyday life.;
- Wastewater treatment. Recycling and reuse of water can reduce the burden on natural sources.;
- Protection of fresh water sources It is important to prevent pollution of rivers, lakes and
groundwater by industrial waste and household garbage;
- Raising public awareness.Educational campaigns help to create a responsible attitude towards
water consumption.
According to experts, the introduction of effective water-saving technologies can reduce water
scarcity by 40% by 2050.
