DID YOU KNOW? All life forms depend on water. Water is essential for the creation and functioning of living cells. It is the main component of blood and plant sap, it transports nutrients to living cells and carries away waste products. About 80% percent of earth’s surface is covered with water. The saltwater oceans and seas contain the largest volume of water on earth (97%). The remaining 3% percent is fresh water, but less than 1% percent is available for human consumption; the remaining 2% is frozen in polar ice caps and glaciers. One half of the world's animals and plants live in water. 75% of a living tree is water. 66% of a human being is water. 75% of the human brain is water. 83% of our blood and 22% of our bones is water. Water in our bodies: Regulates
body temperature
Keeps
salt in the body from building up
Carries
food into the organs
Carries
oxygen to body parts
Conducts
electrical nervous impulses
Aids in

Cleanses
the blood in the kidneys
Our food is
largely composed of water: tomatoes (95%),
milk (90%), apples (85%), bread (35%), chicken (74%), and beef (61%).
There is the
same amount of water on Earth today as
there was 3 billion years ago.
Globally, clean water is a life or death issue for one out of every five people. In developing countries, 80% of all disease is spread by unsafe water. Canadians are one of the greatest consumers of water in the world. We use an average of 500 litres per person every day whereas Madagascar uses 5.4 litres per person per day.
