Water is the source of life. It is essential for the survival of all living beings. It regulates body temperature, aids digestion, and facilitates nutrient absorption. Adequate water intake is crucial for overall health, promoting hydration, and supporting vital processes within the body. Conserving and responsibly managing water resources is important for maintaining ecological balance and the preservation of biodiversity. Let’s examine the various ways in which water influences our daily lives.

Some Facts About Water

Water is essential for life on Earth. It regulates body temperature, carries nutrients and oxygen to cells, cushions joints, protects organs and tissues, and removes wastes. The human body is made up of 60–70% water.

  • Water is called a “universal solvent” due to its unique molecular structure, with polar covalent bonds, enables it to dissolve a wide range of substances. This property facilitates the transportation of nutrients, and the regulates temperature in living organisms
  • Water is the only substance on Earth that naturally exists in three states: at normal temperatures liquid (water), freezes into ice (solid) at 0°C (32° F), and boils into vapour (gas) at 100°C (212 °F).
  • Most substances become denser when they solidify, but solid water or ice is actually less dense. This property is essential for the survival of aquatic life in cold temperatures as ice floats on water. If ice sink, it would eventually freeze the entire body of water making it unbearable.
  • Almost all of Earth’s water is in the oceans, and most freshwater is in ice. 1.7% of the world’s water is frozen. 68.7% of the fresh water on Earth is trapped in glaciers.
  • Water molecules are made up of two hydrogen atoms and one oxygen atom. Unlike other liquids, water expands when frozen. Water freezes into a solid state at 0 degrees Celsius or 32 degrees Fahrenheit. 

What is the Importance of Water?

Water is essential for life as it plays a critical role in many biological processes. In the absence of water, humans can survive only for a few days because it is necessary for maintaining cellular balance and sustaining life. Water’s special characteristics help ecosystems and maintain environmental balance. Lack of clean water poses challenges for communities in fulfilling basic needs, achieving economic growth, and protecting the environment.

Importance of Water in the Environment

Approximately 71% of the Earth’s surface is covered by water, mainly in the form of seas and oceans, which account for around 96.5% of total water volume. However, only a small fraction, 1%, is suitable for use. Ecosystems depend on water for a variety of purposes:

  • Water provides oxygen, nutrients, minerals and has a vital role in metabolic processes like Photosynthesis and respiration in plants and animals.
  • Water also conserves most of the diversity. It supports the growth of vegetation, provides food and shelter for many organisms.
  • Inadequate water resources can lead to ecosystem imbalance, habitat degradation, and loss of biodiversity.

Importance of Water in Agriculture

Water is essential for crop production and raising livestock.

  • About 70% of freshwater from various sources including surface water, groundwater, rainwater, and municipal water systems is dedicated to agriculture.
  • Agricultural water is used for irrigation, pesticide and fertilizer applications, crop cooling, and frost control. Irrigation systems accounts for 80 to 90% of total agricultural water consumption.
  • Adequate water supply is crucial for enhancing agricultural yields and livestock hydration. It ensures food security and maintains livelihoods.

Importance of Water for Industries and Economy

Water serves a crucial function in the manufacturing industry. Water is essential for various industrial processes, such as manufacturing, power generation and for waste disposal.

  • Many industrial manufacturing processes are based on use of water as a solvent in chemical reactions or cooling equipment used in creating their products.
  • In addition, industries also generate profits through water-based activities such as tourism, fishing, and shipping. Fishing in both saltwater and freshwater is a significant food source for many regions worldwide.
  • Hydroelectricity, also known as hydropower, is a low-cost, eco-friendly renewable energy source that uses the energy of running water to generate electricity.
  • However, industrial activities can lead to water pollution and resource depletion, emphasising the need for sustainable water management practices to support economic growth without compromising environmental integrity.

Importance of Water for Human Health

The water in human body percentage ranges from 55 to 78%. Normally, the human body needs 1 to 7 litres of water daily for proper function, based on various factors like activity level, temperature, humidity, and other factors. Water intake includes not only drinking water but also water from food and drinks.

Water Problem in the World and Solutions

Despite its critical importance, access to clean water is still a significant challenge for many people worldwide.

  • Factors such as population growth, urbanization, pollution, and climate change lead to water scarcity and contamination issues.
  • Poor management of wastewater from urban, industrial and agricultural fields contaminates drinking water including groundwater due to leaching of chemicals like arsenic, fluoride, and lead. It can lead to health risks.
  • Diarrhoea, caused by unsafe drinking water and lack of sanitation, can be fatal, especially for children. Insufficient access to water could result in neglecting handwashing, which raises the likelihood of diarrhoea and other illnesses.
  • Although diarrhoea is the most commonly recognized illness associated with contaminated food and water, there are other risks such as diseases caused by parasitic worms by coming into contact with contaminated water.

Various solutions can be:

  • Investment in water infrastructure, water conservation policies, and community involvement is crucial to overcome these issues.
  • The reutilization of wastewater for recovery of water, nutrients, or energy.
  • While the reuse of wastewater and sludge is common worldwide, much of it is used informally or inadequately treated, risking human and environmental health.
  • Safe utilization of wastewater can have numerous benefits, such as enhancing food production, improved ability to withstand water and nutrient shortages and improved circularity within the economy.
