Water Recycling - From Toilet to TapDrought, increasing populations and shifting rainfall patterns are placing increasing pressure on our water supply. But what about all that precious liquid we flush away; could our waste water be safely recycled for human consumption? In south-east Queensland a controversial multi-billion dollar scheme is planning to recycle water from treated sewage. Supporters of the initiative believe it will provide a much needed top-up for falling dam levels. But critics claim the technology can't guarantee the water is clear of dangerous contaminants. Mark Horstman wades into the debate to see if the water is safe enough to drink.Vitamin DWe're told to keep out of the sun - so what are you to think when your doctor tells you that you're not getting enough of it and as a result you now have a serious vitamin D deficiency? Vitamin D deficiency has been linked to a number of bone and muscle diseases (including osteoporosis and rickets). And more and more research is turning up a plethora of diseases that are strongly linked to low levels of vitamin D in our bodies. If that isn't enough to make us strip off in broad daylight then the knowledge that your risk of mortality, independent of other diseases, is also increased if you're low in vitamin D, may prompt us to venture safely out into the sun. Have we taken our fear of the sun too far? Dr Norman Swan soaks up some rays to find out what is really going on. Rob HarcourtMarine biologist Rob Harcourt has had a lifelong love affair with the ocean and particularly what lies beneath the surface. His desire to capture what he sees in this underwater wonderland has led to an incredible collection of photographs, which he hopes will inform and inspire people more at home on terra firma |
