Chemical and biological pollution is far, far worse to humanity and the food chain than radioactive water leaking into the sea.
There were entire studies done on this. Yeah, it's shitty, there's no denying that, but the average person doesn't understand order of magnitudes when it comes to Curies or Becquerels. Suffice to say, the dilution of tritiated water (which is the issue here) really isn't a public health concern. It's hard to make a good argument online about it, so I tend to stay out of them (plus, most people make up their minds and can't be convinced otherwise). People fear what they can't see -- which is ironic, because no one seems to take COVID seriously -- but I digress.
But, succinctly, the burning of coal for power has put more radiation into the atmosphere than any nuclear plant, or nuclear weapon, ever has.

That list continues on and on, just hard to get some of them because they're subscription only material. There's no nuclear power conspiracy. We don't make much money off of it. Coal, gas, oil -- now that's the money you want to trace. These people don't care about anything, just the accumulation of wealth. Most folks in the nuclear industry understand that what they do is far better for the environment
