The main techniques we have now will make the planet uninhabitable even if nothing goes "wrong." Pollution is an ongoing disaster.

I think it's clear we should be spending more time, money, and effort on truly renewable and environmentally friendly power sources. People have been turning that discussion into a "nuclear or not" debate for a long time, which has certainly hampered whatever progress we have made in that direction.

If instead of containing Fukushima we bombarded the area with nuclear bombs, it still wouldn't leave the planet uninhabitable.

Even on years with major nuclear disasters, coal energy production kills more people than nuclear plants. Proper nuclear plants are the second safest option after hydro, and we can't get all our energy from hydro unless we start using much, much less energy.
