Well, I believe the factual content of what you said, I'm just surprised you'd seriously use this as an argument in favour of nuclear power, because the fact that wildlife thrived is so intimately connected with the fact that a nuclear meltdown happened.

Is it the kind of wildlife we want to be reproducing?

Is it the kind of wildlife you want as a pet?

Is it the kind of wildlife you want to eat?

No, this is not actually a good thing.
