The Indispensable Liquid

15 Nov 2013                    

Many of us know that an average adult’s body is made up of roughly 70% water, but why is this necessary? Why is water so important in sustaining life than any other substance? Is this the reason why the Earth is the only planet known to humanity with life?

Many believe that water was crucial in creating Earth’s first life forms, by serving as a medium in which organic compounds could mix with one another and produce simple cells. These cells were the building blocks of evolution, paving the way for the formation of complex animals and plants.

It is evident on how water played such an important part in our existence. Water acts as both a solvent and a delivery mechanism, transporting essential vitamins and nutrients to body cells for energy. It also flushes out harmful toxins, regulate body temperature and aids metabolism. Without water, the body is akin to a machine without oil. It will begin to overwork and slowly deteriorate, eventually breaking down.

Many scientists believe life without water is still somewhat possible. As long as there is a substitute liquid, life may still exist. Many alternatives have been proposed as a possible scenario for life in other planets. However, none of them seem to be able to serve as a proper replacement for the life-giving properties of water.
