Water Water Everywhere?What about it? It’s a cycle right?

What is water?Chemical substanceChemical Formula: H2O

One Oxygen, Two Hydrogen Connected with a Covalent Bond

State:Liquid in ambient conditionsAlso exists on earth in

solid state (ice) Gaseous state (water vapor / steam)

TidbitsCan also exist as liquid crystal state (near

hydrophilic surfaces)Using standard chemical compound

nomenclature it is…dihydrogen monoxide

Fast Facts70.9% of Earth’s SurfaceVital for all forms of lifeWater Breakdown

96.5% is found in oceans1.7% is found in groundwater1.7% is found in the glaciers and ice of

Drinking WaterEssential to humans and other lifeformsAccess has improved but…

1-2 Billion (depending on source) lack access>2.5 Billion lack access to adequate sanitation

(see the problem?)

Clear correlation between access to safe water and GDP per capita

Predictions for …

2025: > ½ of the world population will face water-based vulnerability

2030: Some developing regions of the world, water demand will exceed supply by 50%

EconomyFunctions as a solvent for a wide variety of

chemical substances and facilitates industrial cooling and transportation.

Approximately 70% of the fresh water used by humans goes to agriculture.
