Water – Our Most Precious Resource

Image

The United Nations has declared August to be National Water Quality Month to bring awareness of the importance of water, to appreciate and protect our water resources, and to make the most of the relatively small amount of fresh water available.  

Water is what makes our planet so unique and virtually everything on our planet relies on it. Having clean water is vital to our individual health, our collective agricultural needs, and the needs of our environment. It is the foundation of all life and important to sanitation, human rights, urbanization, sustainability, economic growth, etc.

Unfortunately, clean water is often taken for granted, especially by developed countries. Water is used for everything from drinking to recreation without a second thought. But not all water is created equal and having immediate access to clean water is not to be taken for granted..

What are the Problems?

Population growth

Global water scarcity is by and large the product of the massive population growth that has been taking place over the last century. It is no easy task sustaining the needs of over 7 billion people.  With more people comes more demand for water.  

Water pollution

Water pollution is a major problem in today’s world.   According to the United States Environmental Protection Agency, 40% of the nation’s waterways are suffering from water quality problems, and 207 of our 397 national parks — 52 percent — have waterways that do not meet appropriate water quality standards under the Clean Water Act.  Polluting an already scarce water supply further reduces what can be safely used.

Where Do We Get Our Water?

Even though water makes up over 70% of Earth’s surface area, the total amount of freshwater found on Earth only makes up around 3% of the water supply, 1% of which is easily accessible.

Fresh Ground Water 

This encompasses all the aquifers and other sources of water buried underground.

Fresh Surface Water 

Surface water includes all the water found in our lakes, rivers, and other terrestrial sources. 

Know Your Watershed

Image

Watersheds are areas of land that separates water flowing to different large basins. This water often starts at snowpack at high altitudes, but can begin at any elevation above sea level or even from springs deriving from underground aquifers. The water is led by gravity through the landscape and joins up with other water streams to form rivers, which eventually make their way to the ocean. In the United States, all water falling to the east of the continental divide eventually makes its way to the Atlantic Ocean and Gulf of Mexico.  All water falling to the west of the continental divide makes its way to the Pacific Ocean. This is important because liquids, fertilizers, waste, etc. on the surface can be swept up the movement of water in the watershed and make its way to the ocean where it pollutes marine life.

Rivers on watersheds are often used to produce energy from hydroelectric dams and hydrokinetic current turbines.  The U.S. Department of Energy and its laboratories work to make these facilities more powerful and efficient, as well as cleaner and safer to operate for water purity and the protection of aquatic life.

Ocean Water

As mentioned, the ocean not only comprises 67% of the surface of the planet.   While we obviously do not drink ocean water, that does not mean we are not reliant on it. In fact, our very existence depends on it because   

• It is the Earth’s largest carbon sink and is the primary driver of weather and climate. 
• It is the biggest and most diverse collective ecosystem on Earth – one on which we depend for food and products.

Despite it being a central to our climate and weather as well as food, the ocean is polluted to the point there are dead zones where nothing can live and floating in the Pacific Ocean Is an island of trash twice the size of Texas called the Great Pacific Garbage Patch: If we do not see it, it is out of mind.  But as the ocean goes, so goes the planet. 

Things You Can Do to Be Active and Protect Your Water During Water Quality Month…..and Throughout the Year

Understanding the source of drinking water is just the beginning. By getting more acquainted with where our water comes from, you can figure out where and how your local community gets their water. Knowing where your water comes from makes it easier to appreciate the quality of your local waterways, and can motivate you and your community to keep these water sources as clean as possible. In order to learn more about the water that comes out of your faucet specifically, you’ll want to read through your local water quality report. Most local municipalities offer a general report on their official website that should be updated annually.

• Learn about the current water crisis and water pollution issues
• Monitor water quality
• Reduce your household’s water usage by not wasting water while washing dishes, showering, or brushing your teeth
• Avoiding over-watering your lawn and use rain barrels to collect rainwater for landscaping use
• Check automatic sprinkler systems for proper coverage and to make sure there are no leaks or broken heads
• Volunteer in a local stream or beach cleanup or adopt a watershed with friends and family. 
• Plant trees to prevent erosion
• Pickup after your pet as animal waste is full of nitrogen which can remove oxygen from the water leaving it unusable for aquatic life
• Do not hose down your driveway, patio and sidewalks – use a broom instead
• Do not flush expired or unwanted medication down the toilet because these products have toxic chemicals
• Take used oil or antifreeze to a service station or recycling center for proper disposal
• Use environmentally friendly soaps and cleaning products
• Don’t use fertilizer with phosphorus which is toxic to marine life, opting instead for organic materials
• Wash your car at a car wash which will prevent toxic chemicals from going down the storm drain and into the watershed as car washes drain into sewer systems so the water can be treated and reused – that is unless you use environmentally friendly detergent and a bucket to empty the soapy water down the sink rather than the gutter and storm drains

Together we can make a large impact this month. Spread the word that all of August is National Water Quality Month!

The human body is almost 80% water. Therefore, it is not surprising that this substance plays such an important role in our lives. Without water, a person can survive only a few days. Water deficiency adversely affects the functions of all organs and systems. For normal life, it is necessary to constantly replenish the body’s reserves with high-quality drinking water.

Why is the importance of water in human life

At first glance, there is no shortage of water on Earth. However, when we consider the role of water in human life, we mean fresh water. And its reserves are relatively small. Only 3% of the total water resources of our planet.

Rice. 1. Hydrosphere of the Earth.

Mostly fresh water (99%) is concentrated in glaciers, on mountain tops, in the bowels of the earth. Therefore, only about 1% of fresh water is available to us. But if this volume is distributed evenly, then it will exceed the need of the Earth’s population by 2-3 times.

When we talk about the importance of water for humans, it is not only and not so much about the water we drink, but also about the fact that plants and animals will die without water, which means there will be no food. Therefore, there should be enough water not only for direct consumption and cooking, but also so that there is something to cook food from.

Rice. 2. The water cycle in nature.

Water plays a primary role in the life of all living organisms. Man is no exception. Most of the water contains the human brain – up to 85%, muscle tissue – about 70%.

Water plays an important role in digestion, promotes rapid and complete absorption of nutrients. Water also removes the end products of metabolism, toxins from the body.

Water is the best solvent. It dissolves oxygen, carbon dioxide, many salts and other substances.

Water takes part in the thermoregulation of the human body, it is necessary for lubricating the joints. In addition, water:

• humidifies the inhaled air;
• maintains skin elasticity;
• regulates blood pressure in the vessels;
• protects the kidneys from the formation of stones;
• acts as a shock absorber for the spinal cord;
• protects vital organs.

This is briefly about the main thing, what role water plays in human life, why it is so important to us.

Water consumption rate

During the day, the human body on average loses about 3 liters of water, which is excreted with sweat, exhaled air, feces, urine. Therefore, replenishment of losses is required to prevent dehydration. The daily consumption of water by an adult should be at least 2 liters in pure form. Better if it is bottled drinking water.

Rice. 3. Bottled drinking water.

What have we learned?

Water is vital for the human body, it takes part in metabolism and other processes occurring in cells and tissues, maintains the structure and functioning of organs and systems normally. Therefore, it is necessary to satisfy the daily need for drinking water in full. In a message in grade 5 in a biology lesson, you can talk about the importance of water in human life.

Water plays an incredibly important role in human life. Also, all plants and animals need water to survive. Without water, there can be no life on earth. Why is water so important and what is its significance?

Water in human life: the functions it performs

60 percent of our body weight consists of water. Our bodies use water in all cells, organs and tissues to regulate body temperature and maintain other bodily functions.

Since our body loses water through breathing, sweating and digestion, it is very important to replenish water by drinking liquids and eating food that contains water.

Let’s look at all the important functions that water plays in human life …

Water in human life: the functions it performs

Water helps to create saliva

Water is the main component of saliva. It is critical for breaking down solid foods and maintaining oral health. If your mouth is drier than usual, increase your water intake. If this does not help, see a doctor.

Diffusion around us: examples

Water regulates body temperature

Hydration is critical to maintaining normal body temperature. Our bodies lose water when we sweat and are exposed to hot environments. Sweat keeps our body cool, but body temperature will rise if we don’t replenish lost water.

Lack of water leads to dehydration, which in turn leads to a decrease in electrolyte and plasma levels.

Water helps cognitive function

Proper hydration is critical to maintaining cognitive fitness. Studies have shown that insufficient water intake can negatively affect our focus, attention, and short-term memory.

Water protects tissues, spinal cord and joints

Water helps to lubricate and cushion our joints, spinal cord and tissues. It helps us to be more physically active and reduces the discomfort caused by diseases like arthritis.

It removes waste from our body through sweating, urination and defecation

Our bodies use water for sweating, urination and bowel movements. We all need water to replace the fluid lost through sweating.

We also need water in our body systems to avoid constipation. Drinking enough water helps our kidneys work more efficiently, thus preventing kidney stones

Water maximizes our physical performance

Drinking plenty of water while exercising, exercising or just moving around is extremely important. The level of water in the body also affects our strength and endurance

Water in the human body depending on age

It helps to increase energy levels

Drinking water helps to increase the metabolic rate. Raising it has a positive effect on energy levels. Drinking 500 milliliters of water can increase the metabolic rate by 30 percent in both men and women.

Exercising in hot weather without hydration can lead to serious medical complications. In fact, extreme dehydration can sometimes end in death.

What are the unique physical properties of water?

Water prevents general dehydration

Dehydration is the result of the body not getting enough water. And, since water is critical to the success of many bodily functions, dehydration can be very dangerous. It can even lead to death. Severe dehydration can also lead to serious consequences, including:

• swelling in the brain
• kidney failure
• seizures

Be sure to drink enough water to replace lost moisture from sweating, urination and defecation to avoid dehydration.
