I suppose on the plus side, if the older satellites fall and burn up at least they are not adding to all the space clutter we've put up there over the decades..

MP>> Maybe Global Warming is not a disaster, just a correction back >> to 'normal'.. MP>Agree. We have a hand in accelerating the process, but not in creating it. Yes, there's been a lot of brainwashing over the years about Global Warming and Climate Change and most who think it's a man made disaster don't pay attention to the money being made using it as an excuse to do something or change prices. If you blame yourself for global warming you are less likely to complain about paying $4+ a gallon (usa) for gasoline and higher taxes and such.. --- * SLMR Rob * They made us eat porridge...it was a grueling experience. * Origin: Capitol City Online (1:2320/107) ----------------------------------------------------------- [Voltar]
