If they themselves really believed it was a perfectly natural phenomenon, I don't think they would need to constantly reassure themselves that this is supposed to be happening.
Why is it that pouring tons of salt in my glass of water can't replicate this effect, no matter what kind of salt I put in it?
Why is it that other lakes that are saltier are not experiencing the same thing?
It's ok though, because it's "natural" :rolleyes:
