The only substance that can be in all 3 physical states altogether within a
reasonable temperature range. Earth is situated in a way that allows water
vapour/water/ice to be present simultaneously. It has a high retention rate
(holds high temperatures) and balances heat extremes. Water vapour holds
and moves heat around. Positioning of hydrogen and oxygen atoms slightly
polarizing, it makes water a good solvent. Water’s structures (hydrogen and
oxygen) gives itself a slightly polarized energy to create bonds.
It is less dense than water, which allows it to float. It acts as an insulator over
lakes and other large bodies of water, so that life can continue underneath.
Water and You
Since humans are made up of mostly water, they are susceptible to
everything that is in the water.
Turgidity is what keeps humans from looking dehydrated and shriveled.
Average home consumes about a million litres of water every few years.
Religions and Water Symbols
There are two different kinds of water: 1) saltwater – dangerous and kills
agriculture; 2) freshwater – cleans and refreshes. It comes down from the sky
or a mysterious source.
In different traditions, water and gardens are very important to the tradition.
Whether it is its existence or sound. It symbolizes cleansing.
Water as a public good- used for drinking.

is a metaphor for the soul or life itself.
Shinto tradition: a place of rivers and movement of water is a place of
transforming power. You are supposed to gather or garnering these falls of
Water is used a lot in advertising- it connotes sex appeal and “hot”/”cold”
Ground water flow occurs in the soil
Water in the World
Most of the water in the world is saltwater, and thus not for drinking. A small
percentage is freshwater. There is not a lot of water for human access.
World water consumption is increasing.
Global water situation: there are more than 2 billion people who are under
water stress, which means they are not accessing enough water. Many
people rely on groundwater and springs, which are essentially tapping into groundwater as opposed to lakes. Some of it are from aquifers from many
Most of the water withdrawals are from agriculture. Currently, it is very
Water pricing: governments subsidize this. Citizens normally do not pay the
full price of water.
There is a lot of agricultural water use, then domestic usage for those in
developed countries and then industrial.
About 1 billion people still have little to no access to freshwater and is
leading to many deaths.
E.g. the Nile River is essential to the existence of Egypt. Water lines
