Welcome!
In our day to day lives, we are continually bombarded
with never-ending tasks and chores. It is very easy to take
the simple things in life for granted. Water is one of those
things that always seems to be neglected.
Covering more than 70% of Earth's surface,
water is the most common substance on Earth. It is basically
everywhere; oceans, rivers, lakes, the ground, and the air we
breathe all contain water. Without the presence of water, there
can be no life. However, water is not only a necessity. It is
also used both directly and indirectly for entertainment, and
as a way to improve the quality of our lives.
Water is an odorless, tasteless, transparent liquid that is
colorless in small amounts but exhibits a bluish tinge in large
quantities. The percentage of available worldwide water that we
use today can be astonishing. Almost all of it (approximately
97%) is in the oceans, but this water is too salty to be used
for drinking, farming, and manufacturing. Only about 3% of the
world's water is fresh. Most of this water is not easily
available to people; 2% is locked in icecaps and other glaciers,
and half of the 1% leftover is beneath the Earth's surface as
groundwater. Fortunately, there is as much water on Earth today
as there ever was, or ever will be, because of a continuous water
cycle.
