Shrinking water supply poses threat to peace
“Water, which is essential for life, costs nothing. On the other hand, diamonds, which are essential for nothing, cost a lot.” Unfortunately, the world has changed considerably since an 18th century economist made this remark.
What was true over 200years ago is certainly no linger true now. in a number of countries people pay as much for water in their homes as they do for electricity.
Like health, we ignore water when we have it—unless there are floods, of course. Once there is a threat to our water supply, however, water can quickly become the only thing that matters. We know only too well that, without water, there can be no life.
The situation is now becoming so bad that environmentalist feel it may be necessary to shock the world into saving water in a similar way to the shock caused by the oil crises in the 1970’s.
At that time, the oil crisis became such a serious threat to the lives of everyone in the developed countries that it made people conscious of the importance of saving oil and provided powerful encouragement for governments to look for other forms of energy.
The result undoubtedly was of major benefit to energy conservation.
There is now no linger and unlimited supply of fresh water. About 97 per cent of the planet’s water is seawater. Another 2 percent is locked in icecaps and glaciers. There are also reserves of fresh water under the earth’s surface but these are too deep for us to use economically.
