Around 70% of earth is covered with water. Our body consists of 75% of water. On average, a human body has up to 42.5 liters of water and just a lack of 2.4 liters can cause dehydration. We can survive for 3 weeks without having food but we start to die within three days without water. It is also true that there is no alternative to water. So, it is clear that how important the water is for the existence of life.
If we have 66% of water on earth, the question is why we are still facing scarcity of water. It is due to just 3% of fresh water is available for drinking purpose. Rest of the water is sea water that is salty and of no use.
Why Should We Save the Water?
70% of water is used by agriculture. A lot of water is required for farming across the world to harvest healthy crops which need huge quantity of water. Around 26 gallons of water is used to produce one ear of corn. One loaf of bread is prepared with 300 gallons of water. 120 gallons of water is used for one egg. A bushel of wheat takes 12000 gallons of water and up to 1400 gallon is used to prepare a fast food meal like burger, coke, and fries.
20% of water is used by industries in the manufacturing process and as a coolant. There is huge demand of water in industries. The rest of 10% of water is used in household purposes. With the increasing density of population, it is getting even harder to meet the need of water. If 1000 liters are required for 1 cubic meter, it is increasing at 64 billion cubic meters per year.
There is three fold rise of the extraction of fresh water over the past 50 years from glaciers. Because of the recent changes in lifestyle, there is huge demand for water. It also means the rise in demand of water for power supply.
Even in our environment, we need water to survive. It maintains life balance on earth. So, wastage of water may lead to water scarcity and balance of life would come in danger. Not only humans, wastage of water also affects every species in the world. According to the Bureau of Reclamation reports, around 21 aquatic species have been extinct over the past 100 years in the US alone because of disturbance in the ecological balance, usually due to population explosion and rise in demand of water.
Saving water prevents the risk of droughts and other natural calamities. We should learn to reuse water in as several ways as possible. Saving water is very important for upcoming generations. Unless we get concerned about water from today, next generation won’t have enough water to survive.
We should save water as we have to save plants. The oxygen on earth and most of the food is available from plants. Water is needed also for plants. Most of the water is used in development and recreation purpose. Lots of fresh water is being used in swimming pools, parks, fountains and a lot of things. We should cut off the wastage of water to maintain beauty of the city.
