Science on Saturday Night: Save Water, Save the Living

Water is an interesting issue. As with all of Nature it is a symbiotic factor in a greater whole, and an element all life depends on.  We will kill each over water.  In our slumber we have assumed water will always be there for us – Clean water to drink, waterways for recreation, healthy rivers and oceans to supply us with healthy fish, water to wash our cars, water to green our lawns and landscapes, water to bath and shower in, water to brush our teeth with, water for our swimming pools. We can conserve, and consciousness is growing, but what about the new billions of people coming into the planet over the next few decades.  As water levels go down, the pollutants in it get stronger.opening 5

Climate change will affect the water security of developing countries. Freshwater is a scarce resource. Only 2.5 per cent of the 1.4 billion km3 of water on Earth is freshwater fit for human consumption, and most of this is inaccessible — nearly 70 per cent is locked up in glaciers, snow and ice. Our greatest source of freshwater is the 8 million km3 of groundwater, with only 0.3 per cent of freshwater (105,000 km3) being found in rivers, streams and lakes.

Here are some water facts to remember:

  1. Less than 1% of the earth’s water is suitable for drinking
  2. More than a billion people around the globe survive on just over 1 gallon (4 liters) of water per day
  3. Potentially more than 3 billion people may suffer from water shortages by the year 2025
  4. 66% of the human body is water
  5. A person can only live without water for approximately one week

There are several ways we can do to overcome the water crisis:

  1. Promote the movement of planting trees
  2. Promoting water-saving movements
  3. Land conservation
  4. Forest conservation and watershed areas
  5. Build a water reservoir
  6. Constructing absorption or biopore wells
  7. Tackling water sources from pollution such as factory wastes, etc.

You can save water without changing your life routine. Some activities you can do to save water is turning off the tap when you brush your teeth – this can save 6 litres of water per minute. The other activities are place a cistern displacement device in your toilet cistern to reduce the volume of water used in each flush, take a shorter shower because shower can use anything between 6 and 45 liters per minute. Always use full loads in your washing machine and dishwasher – this cuts out unnecessary washes in between and there are more ways to save water in the daily routine.closing

Let’s join our hands in saving water as much as possible. Here are the different ways we can follow to save atleast some amount of water per day.
