The Importance Of Water


With two thirds of the earth's is surface covered by water and the human body consists of 75 percent of water.

Thus water is one of the most important elements, responsible for life on earth.

In our body water does so many important task, like transporting, dissolving, and replenishing nutrients and organic matter, while carrying away waste material. In our body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions. The beauty with water is does similar work when it circulates through the land on earth, it cleanses, rejuvenates, distributes and so much more.

Our average adult body contains 42 liters of water and with just a small loss of 2 to 3 ltr,  he or she can suffer from dehydration, displaying symptoms of irritability, fatigue, nervousness, dizziness, weakness, headaches

The human brain is made up of 95% water; blood is 82% and lungs 90%.

Water is one of the most important substances on earth. All plants and animals need water to survive. If there was no water there would be no life on earth. Apart from drinking it to survive, people use for water other things like washing, cleaning, watering etc .

Water Important for Living Organisms

In our human body, Water carries nutrients to, from, and within cells.

Transport: the blood is mostly water

Chemical reactions: water is a solvent and we need it for the body to operate..

Water is the solvent that transports many essential molecules and other particles around the body like nutrients and waste products from the body's metabolic processes.

Water-based organisms such as fish require water even to breathe. These organisms directly breathe oxygen dissolved in water. This is why if you see fish taken out of water, you will see it suffocate and die.

All Living organisms need water to survive.

Droughts and Floods


A drought, very simply defined, is an extended lack of rainfall.

Many plant species, such as those in the family Cactaceae (or cacti), have drought adaptations like reduced leaf area and waxy cuticles to enhance their ability to tolerate drought. Some others survive dry periods as buried seeds. Semi-permanent drought produces arid biomes such as deserts and grasslands. Prolonged droughts have caused mass migrations and humanitarian crises. Most arid ecosystems have inherently low productivity.


A flood is an overflow of water that submerges land that is usually dry. It is a covering of land by water not normally covered by water.

Flooding occurs most commonly from heavy rainfall when natural watercourses do not have the capacity to convey excess water. However, floods are not always caused by heavy rainfall. A flood is an overflow of water on land which is usually dry.

Extreme flooding can also be caused by a tsunami or a large storm that causes a storm surge. Floods that happen very quickly are called flash floods.
