> ... which for Fukashima was apparently 150,000

To put it in perspective, the prediction for the number of climate refugees vary, but papers seem to put the number somewhere between 150 and 300 million by 2050.[1]

That's about one Fukushima every five to eleven days, starting from now and continuing until 2050.

Think about it.
