Water

• The ocean is the world’s thermostat, keeping the earth’s surface temperature within certain limits

• Water vapor provides the right amount of cloud cover

• Rain water cleanses the earth

• It is a universal solvent. In the human blood stream it holds in solution the minimum of 64 substances. Any other solvent would be a pure sludge.

• It has a high specific heat, so that chemical reactions within the body are kept rather stable

• Other than bismuth, it is the only liquid that is lighter when frozen, allowing lakes to freeze from the top down and not kill all the fish
