How we learned to hate the Nuke and ruined (?) our own environment along the way

This is a bit late, but I didn't want to step on the feet of my UnChristmas Story, nor Christmas itself.

The answer to the titular question is: 1970s environmentalism. At one point in the 1970s, it was hoped that 200 "breeder" reactors would be online by 2000, which would have reduced our carbon output by 1/3.

Sadly, President Carter, aided no doubt by a 1973 lawsuit by the Natural Resources Defense Council and Scientists Institute for Public Information, killed the plan.

Of course, back then nuclear was the Devil, the environment was the Endangered One. Now, carbon is the Devil, and the environment is the Even More Endangered One. Sadly, if we had only chosen the proper course 30 years ago, we might have been able to knock a prefix and suffix off of endangered (that's a beginning and an ending; for those of you who might not get it - that means we'd be left with simply Danger.)

Choices choices. And of course their consquences, people.

Here's the reason link from pre-Christmas week.
