Every plant animal, and human being needs water to stay alive, due
to the fact that all the life processes require water. People depend on
water to stay alive and for their way of life. Water is needed in homes
hygiene and for food preparation processes, and it's also needed in
factories to manufacture things such as automobiles. Water
is needed for irrigation, allowing crops to be raised in regions that
don't get much rain.
Every organism consists mainly of water. Your body is about 65%
water-- the brain is about 70% water, blood is about 82% water, and the
lungs are nearly 90% water. All living things need a lot of water to perform
life processes.
In our homes, far more water is used than is needed to simply stay
alive. For many people, such water is a luxury. Millions of homes in
Asia, Africa, and South America have no running water, so the people
haul water manually, often carrying it from long ditances to their homes.
