It would seem that those of my ilk are soon to be found on the Endangered Species List:
"A study by the World Health Organisation (sic) found that natural blonds are likely to be extinct within 200 years because there are too few people carrying the blond gene. According to the WHO study, the last natural blond is likely to be born in Finland during 2202."
I don't know if this is some sort of thinly veiled anti-miscegenation propaganda, or what. But if our inherent genetic recessiveness doesn't do us in, the lack of ozone will. Anyway, I recently concealed my blondeness; I am now superficially a brunette (gasp!). Nonetheless, I would like to be given special status as a fragile member of the ecosystem. Seriously though, worrying about a future without blondeness (though any lessened diversity seems sad to me), is far less disturbing to me than the loss of an actual species, say, the silver spotted butterfly, or humpback whales.
Here's a theory on the introduction of blondeness into the pool of Homo Sapiens. I have to say, it seems a bit like forcing on a shoe, but it amuses.
Anyway, even if the gene goes the way of the Dodo, there's always peroxide. Ask Paris, she knows.
