utilities according to the principles of private enterprise. As far as our<br />

water supplies are concerned, this development is particularly alarming<br />

because there is no substitute for water, just as there is none for the<br />

air we breathe. Experience has shown that, when water is traded just<br />

like any other economic commodity, the quality deteriorates, prices<br />

rise, all form of democratic control is lost and political decision-makers<br />

become susceptible to blackmail.<br />

In order to reinforce these statements, I will need to take a closer<br />

look at various aspects relating to our use of fresh water.<br />

3.1 Water in Abundance<br />

More than 75 per cent of the Earth’s surface is covered in water. This<br />

figure creates the impression that we will always have an adequate<br />

supply of it and one which could never ever run dry. But appearances<br />

are deceptive. Only around 2∙6 per cent of the world’s water reserves<br />

are made up of fresh water sources and only just under 0∙6 per cent of<br />

these are available to us. The remainder – approximately 2 per cent<br />

– is locked away out of our reach in glaciers, the polar icecaps and<br />

perpetual snow.<br />

The fresh water at our disposal is extracted from rivers, lakes,<br />

springs, wells and subterranean water deposits, so-called aquifers.<br />

Our planet’s fresh water reserves are distributed in the following way:<br />

glaciers and polar icecaps approximately 77 per cent, ground water to<br />

a depth of 800 metres approximately 10 per cent, and ground water to<br />

a depth of between 800 and 4,000 metres approximately 12 per cent.<br />

Ground humidity, lakes, rivers, the atmosphere, vegetation, animal<br />

and human life together account for less than one per cent.<br />

The total amount of water on the planet remains constant and<br />

it is always the same water we use to satisfy our needs. The tears<br />

shed by a sad dinosaur many millions of years ago at the thought of<br />

becoming extinct may possibly be found again today in some beach<br />

café refreshment, and may even have been used in the meantime<br />
