Study on Livestock Pollution Not Sound

Much has been said about cattle that increase carbon and methane levels in the atmosphere. Test were done on cattle in the European Union. Options were considered on how the emissions could be reduced. It was found that dairy and beef cattle contributed 60 per cent of pollution for the whole livestock industry. Because little can be done about body waste emissions, efficiency factors were at the center of the study. Poor land use was the second highest factor in global greenhouse gas emissions after direct production. Pollution for wasted food followed inefficient use of land. As usual the investigators did their calculations on how much pollution could be lessened if their advice was adopted by the livestock industry. It was estimated that the lowest impact would be a reduction of 12 per cent. Optimists in the group said 60 per cent. Somehow consumption of meat was to be reduced. Just how this was to be done was not made clear. With people in developing countrie

Believe it - X-ray with Cellotape

It is possible to see through sticky tape. But such tape can also help you see through things! The action of peeling tape off a roll actually produces x-rays.If the tape is quickly stuck to a finger bones become visible. This was not discovered by someone actually seeing that this happens, even though it has been obvious for anyone to see for years. People are funny that way - put something under their nose and they won't see it. Actually, it was discovered by Russian scientists who noticed that peeling tape from a roll created bursts of x-rays seen on a meter. The Russians increased x-ray emissions by peeling the tape off in a vacuum. The scientists were shocked to make the discovery. They could not believe that no one had actually observed this occurring by trial and error. It works by triboluminescence. When tape is pulled from the roll the sticky acrylic becomes positively charged, while the roll remains negatively charged. For a billionth of a second the negative ions on t

Surely Australia Could Pay a Little More for a Cleaner Planet

It is so strange how support for Kevin Rudd's Emissions Trading Scheme has totally evaporated. Kevin Rudd rightly claims that his backing down from trying to pass the legislation cost him leadership of his party and the country, so great was public support for it then. Times have changed. With big rises in water charges and electricity charges across the country people just don't want a bar of it anymore. The proof of global warming is considerable. Ice is disappearing from the North and South Poles. Those who still contend that it is made up just to get money out of the public must be living on another planet - in their minds at least. No one wants to be paying higher prices for essential items than consumers in other countries, but the world is changing. China is making major changes. to reduce pollution. Finland introduced the world's first carbon tax in 1990. That is two decades ago. Sweden followed in 1991. Great Britain brought in a climate change levy in 20

Beware the Ozone

Ten years ago the ozone layer was a major topic. "The ozone is decreasing," headlines proclaimed. Then, it was just as quickly forgotten. It may not be growing so much but the ozone layer is still causing problems. The weather has been altered. Wet and dry extremes are the result. Desalination programs have been put on the backburner for now. They will be needed soon as the cycle swings back to dry. The ozone hole shifts high-altitude wind circulation southward. Most notable for Australia has been the movement of the Southern Hemisphere jet stream to the south. This has severe effects. For example, in the north Britain has got very cold winters in recent years due to blocking of the Northern stream. Estimates are that Australia's weather has changed by a magnitude of 35 per cent. More rain has been brought here. With the impact from greenhouse gases this water evaporates very quickly, so the overall impact is dryness. With the combination of ozone, greenhouse
