what is the importance of water?

With two thirds of the earth's surface covered by water and the human body consisting of 75 percent of it, it is evidently clear that water is one of the prime elements responsible for life on earth. Water circulates through the land just as it does through the human body, transporting, dissolving, replenishing nutrients and organic matter, while carrying away waste material. Further in the body, it regulates the activities of fluids, tissues, cells, lymph, blood and glandular secretions.

• The need of the hour is to conserve and manage water because although the total composition of water on earth is almost 70 per cent but fresh water reserves are only 2 per cent. Hence, in the present scenario of increasing rate of population, the resources in order to be equitably distributed, should be managed and preserved. we need water for the following reasons:

  • to survive
  • irrigation
  • industrial production
  • maintain the balance in nature

• Some methods that be used to conserve water are as follows:

  • In hill and mountainous regions, people built diversion channels like the guls or kuls of the Western Himalayas for agriculture.
  • Rooftop rain water harvesting was commonly practised to store drinking water, particularly in Rajasthan.
  • In the flood plains of Bengal, people developed inundation channels to irrigate their fields.
  • In arid and semi-arid regions, agricultural fields were converted into rain fed storage structures that allowed the water to stand and moisten the soil like the khadins in Jaisalmer and Johads in other parts of Rajasthan

Balance diet is very important as it provides all the nutrients, minerals, etc. in appropiate amount that are required by the body for proper growth and development.

Water is required by each cell of the body. Water helps in removing toxic elements of the body.

Plant do need oxygen during the process of respiration. This process takes place in mitochondria

Hope this helps,

Water conservation means, to use water wisely and save for our future generation. In present environmental situation water conservation has become highly important because

• No organism can survive without water for a single day.
• We do not have endless supply of water on earth. Though 3/4^thof our earth is water but among that 97% is salt water and only 3% is fresh water and 1% is drinkable as remaining 2% is locked as snow. So all organisms whether plants or animals depend upon that 1% of drinkable water.
• By conserving water we can save our environment. It decreases water pollution.
• Conservation of water also helps to conserve water animals and wild lives that depend upon water.
• Water conservation is necessary for our daily household practices like cleaning, washing, bathing etc.
• Water is necessary for industries and agriculture.
• Wise use of water also helps to save money by reducing demand of water treatment and recycling.

To take part in this noble cause of saving water we need to follow some simple steps:

• Do not waste water and save however possible.
• Turn off the tap while brushing teeth, soaping or shampooing.
• Take care of the pipes whether there are any leakages.
• Take a short shower.
• Water the garden only in early morning to avoid evaporation.
• Grow plants as much as possible to retain the moisture of the soil.

Importance of water harvesting are:

• Helps to recharge the ground water.
• Solves the problem of water scarcity.
• Water can in used in drought period.
• It prevent flooding.

Water is one of the important gifts of nature and it forms the basis of life. It is essential for our survival.No organism can survive without water. Some important functions of water in our body are as follows:

• It helps in digestion, absorption and transportation of food.
• It helps to maintain good health as it removes toxic wastes from our body.
• It helps to maintain proper muscle tone.
• It helps to transport oxygen and nutrients to the cells.
• It helps to regulate the temperature in body.

We use water in our daily activities like drinking, bathing, cooking, washing, gardening, etc.
