What if there weren't any water on earth?
There wouldn't be any trees...or animals...or humans.
All living things need water to live. Next to the air we breathe,
water is our most important need.
Without water, the earth would look like the moon:
The Human body is 70% water. Every system in our
body uses water.
- Water makes up to 83% of our blood.
- Water transports body wastes.
- Water lubricates body joints.
- Water keeps body temperature stable.
- Water is part of cells, which make up all living things.
Human beings can live several weeks without
food, but only a few days without water. Each
day, we must take in at least eight glasses of water.
But drinking water or other liquids provides only
half the water we need. The other half comes from
the foods we eat.
List some foods that have water in them *.
