President Obama's Science Advisor, John Holdren, is for existing nuclear power technology which only uses 1% of the nuclear energy in uranium. This is not expected to last for thousand of years. He is against advanced uranium nuclear technologies and used fuel recycling which can access 99 TIMES more energy. There is enough uranium to provide for all of the world's energy needs for a very long time. Holdren doesn't discuss thorium nuclear power which has a greater amount of energy than uranium. The Sierra Club IS AGAINST ALL nuclear power, including the kind that Holdren supports. Never has any conqueror or dictator taken away something so important as the Sierra Club, John Holdren, and the Natural Resources Defense Council are taking away from the world in nuclear energy. It is unimaginable that Americans are letting this happen.
