- 70 percent of the human body is
water; 83 percent of the human body's blood is water.
- Water helps humans digest food, take in oxygen, transport
body wastes and control body temperature.
- Almost 75 percent of the Earth is covered in water.
- Most of our food is water: tomatoes (95 percent); spinach
(91 percent); milk (90 percent); apples (85 percent); hot
dogs (56 percent).
- The human body needs two litres of water a day in our climate
and can survive only a few days without water.
- Because water continually cycles through the environment,
you could be drinking water that once fell in the Amazon rainforest,
or that was once drunk by the dinosaurs.
- The toilet in your home uses more
water than anything else in the house.
- Around the world, approximately 34,000 deaths occur daily
from water-related diseases.
- Most of the world's water supply is found in oceans; other
sources include glaciers, underground pools, rivers and the
atmosphere.
- The average person in Canada uses
350 litres of water per day. The average person in the UK
uses 175 litres. In Bangladesh, the average person uses 45 litres.
- Around the world, only about seven
percent of the water used goes to households. The other 93
percent is used in farming and industry. In Canada, the ratio
is almost 50-50, with 51 percent of water used going toward
domestic uses.
