To predict that South Africa will run out of drinkable water in a year’s time sounds wonderfully surreal, but it isn’t as far-fetched as it might seem. Southern Africa has already run out of water. In many regions our city planners already have had to put alternative measures in place. Municipalities that have already set about implememting technolgy such as desalination plants or effluent treatement systems should be commended for doing so. Those who still fighting the general assumption that it is too costly for both the consumer and the local authority to implement should stop dawdling and start running through a few worst-case scenarios. Just ask the municipality of the Karoo town such as Beaufort West what it feels like when your local storage dams dries out because of drought. We believe that it is only once more people have experienced first hand what it feels like to be rationed to the number of times you are to flush your toilet in a week or the quantity of water you can drink, that the message of saving and planning for imminent water shortages will start to sink in. If those in the know were not worrried about our water situation, there would have been no need to form the Stellenbosch University Water Institution to look into issues such as water provision, water management and a sustainable environment. It would have not been neccessary to have established a similar venture, the Water Research Commision. For that matter, there would have not been for Sannitree International to look into issues such as waste water treatment, ownership and ways of conserving water. It a fact that water has an influence on our economic development and growth. It is a fact that South africa, at all levels need to act now to play their part n safe-guarding or precious water. In most South African cities, the biggest water users, wasters and polluters are breweries, hospitals, university campuses and business parks. When planning and building news ones, it should become non-negotiable that more efficient water usage practices form part of the exercise. We need more waterless toilet in our new housing develpoments. We need decentralised water treatement systems in new office parks. We need to recycle our water more. We need to indigenous gardens to flourish. For that matter, Sannitree International has introduced the free flowing waterless urinal valve. The new valve is a breakthrough invention because it not only drastically reduces the use and cost of water but it also far more hygienic that conventioanl systems. It is a completely waterless system, simple retro-fit, air-tightseal and deoderising dome to keep ablution facilities completely odourless and easy to clean. We need to use water sparingly. We need to treat it as a priceless, commodity that it is. If we do not take care of our water now, it will come at too costly price for us. And next year might simply come to soon.
The moon has more water than scientist once thought, casting doubt on theories of its creation, according a study. Scientists measured seven samples of magma trapped as “melt inclusions.” within crystals, according to a paper in the journal science. Lower quantities of water and volatile compounds on the moon, when compared with the earth and other inner planets of the solar system, have long been taken as evidence the moon formed during a gained impact that have enough energy to create seas of magma, according to the Carnegie Institution’s Erik Hauri, the study’s lead author.
Today’s finding challenges that view, he said. That findings suggest that the impact from a Mars-sized body that formed the moon was either much hotter or much cooler than previously thought. If the moon impact was cooler, then some material including water wasn’t molten and was locked in thee lunar interior. If the was more energy, then the rocks boiled and created a temporary atmosphere, Hauri said. While the atmosphere would have been dense and short-lived, it might have allowed the still-forming earth and moon to exchange water. The presence of water tells us how much potential it has to sustain our life.
