Nuclear Energy Becoming Less Sustainable. By Brooke Borel, Sydney Cosmos, April 24, 2008. "The case for nuclear power as a sustainable alternative energy source is challenged by new evidence that greenhouse gas emissions from uranium mining are increasing. An Australian report, detailed this week in the journal Environmental Science and Technology argues that the availability of high-grade uranium ore will deplete over time making the fuel more environmentally and economically expensive to extract. The find adds to existing concerns about nuclear energy, such as the problems of disposing of radioactive spent fuel and whether uranium processing leads to the proliferation of nuclear weapons."
