The Earth's Comparative
Water Coverage

70% Water - 30% Land

It is difficult to believe, as Australia struggles through its long running drought, that around 70% of the planet's surface area is water.
As Earth's population increases we must really consider the sustainability of our usable fresh water.
Look around your home, school or workplace and consider where you can begin to save.
Adding water tanks & reusing waste water for gardens and lawns are just two of the methods that you can use to protect your future.


How big are our Oceans?

The Pacific is the largest single feature on the surface of Earth and contains the the planet's greatest heights and depths.

The volcanic cones of the Hawaiian Islands rise higher from the ocean floor (9760 m) than Mt. Everest does from it's base (8850 m) and the Mariana Trench (10950 m) could easily swallow Everest whole.

The volume of all the land above sea level is only around one eighteenth that of the oceans and seas.
