They say this as if it's a bad thing ... yet their type is responsible for the lack of widespread nuclear power, which is g-g-g-global-warming-free. Some countries in western Europe are more than 50% nuclear, and without any Chernobyl-type mishaps. Here, the radical left prevents that, despite the environmental damage they allege from fossil fuels.
Environmentalism is only defined by their narrow agenda.
They also prevent development of our domestic fossil fuel resources. Then they complain about our involvement in the mideast and blame it on big oil greed.
You're right, nuclear is the only future we have if we are to look forward to continuing prosperity and national independence.
