Not a reference to the human ability to maybe walk on water in times of flooding, but a concept currently being dreamed up by possibly unfunded academics looking for research grants.
This follows along the lines of our now familiar carbon footprint in that it seeks to expose how much water we use to produce our food and to include it in labelling at the supermarket.
“If a leading a soil and environmental scientist gets his way, consumers will soon be able to identify how much water is involved in production of their favourite goods with ease at the point of sale and identify what region the water comes from.
Its all part of a push to bring about greater understanding and awareness of the water volumes used to make food and fibre products, especially on-farm and irrigated items, through the introduction of a new water labelling footprint”.
UWA Adjunct Professor, Dr Brent Clothier, urged the introduction of a water labelling footprint, while presenting at an agronomy conference in
One commentator wondered how many millions of litres would be labelled on fish.
The link below provides and interesting insight into the scientific brain that believes that water is a finite resource and that as it is used up it goes POOF and disappears.
It completely overlooks the fact that there is a precipitation cycle.
The world’s total rain precipitation in a year is about one meter and about 200 metres have fallen on the Earth since the Industrial Revolution.
Since the Ice Age ended, enough rain has fallen to fill all the oceans four times.
Since the Dinosaurs died, rainfall has been sufficient to fill the oceans 20,000 times.
It seems the amount of water on Earth probably hasn’t changed significantly over geological time.
