Medical procedures, for instance, rack up massive energy tabs - especially surgeries, emergency services and pathology laboratory tests. "Enormous amounts of energy are required to build and run high-tech systems in common use - MRIs, CT scans, etc. - with many running 24 hours a day," says Pamela Gray, a trustee of the Transition Network, a U.K.-based organization that supports community-level initiatives to improve sustainability and combat climate change. Further, nearly all pharmaceuticals are made from petroleum derivatives, and so are medical materials (think rubber gloves and intravenous tubing).

They've since determined the child was perfectly healthy. "All that, just to find out her head is bigger than normal," says the 27-year-old mother of two in Boone, North Carolina...
...what should you ask, if a doctor recommends a CT scan for you or your child? Brenner suggests the following: is a CT scan really necessary? Might a test that doesn't involve radiation, such as an ultrasound or MRI, do the job?
