If it is so that a human mistake can cause a big number of casualties and massive environmental damage it is far from safe, even if you are very careful.

200 years vs. 70 years. IDK if this is comparable. Also it is so that with nuclear accidents theres a lot of additional environmental damage, not just the human casualties.

Not defending coal mining here, coal is no good energy source by all means.

You mean the modern reactors who are still not in a commercial productive state? But even if these would be NOW ready to actually be available it’s still so that there are a vast overwhelming majority of the old reactors which are not as safe as the meme was insinuating.

“Safe”. Yeah. Let’s talk about Chernobyl, Three Mile Island and Fukushima. All that was kinda not so safe, don’t you think?
