Pollution from burning coal (and other fossil fuels, but mostly coal) kills, depending on which estimate you believe, 10s of thousands, to millions of people
per year, and that is completely ignoring impacts of climate change. Yes, even when you take into account accidents like Chernobyl, and even if you decide to accept the very highest of the total death estimates, it's
still dramatically safer than coal.
Over-reacting to early nuclear disasters and failing to accelerate our build out and continuing with coal for the past nearly 80 years post Chernobyl is, in my opinion, one of the greatest civilizational mistakes humanity has made.
