Some scientist has said that at the beginning human population was coloured "black" on earth and if the human population still survives - it'll turn again in to "black". Maybe some "white" ones would like to hurry that change when they are taking sunbaths
But I know someone who has a desease that's called psoriasis and sunbaths help her with the skinsymptoms a lot during the dark winter-season - and it's cheaper to take them instead of moving with her six-membered family somewhere south and sunny area on earth. And I know that someone has been helped under 18 years of age with acne by taking sunbaths.
There's still a risk and that's great that people has been warned about them seriously. They should also remind that sunburns are also a big health risk (skin-cancer) and that's why everyone should protect themselves during the sunny season.
And Calrissian - I use normally factor 2 to 8 and I don't change much my skin-colour during the summer. But some facial creams has factor 30 in them.

Indeed, it is almost certain that our earliest ancestors were as black as night. In evolutionary terms, as people migrated, skin pigment changed - due to the necessity of gaining Vit'D (primarily).
Culturally, with the intl 'global village', eventually everyone from every country will be a nice chocolatey colour - think 'denzel washington' and 'halle berry'. Personally, sounds great to me.
Yes, there are a few groups of people who benefit from sunbeds ,but 99.97% of people will not.
Factor 2-8, why bother? Are you not aware that those sorts of skin protection are essentially pointless. Scientifically speaking, anything below 30 is effectively useless.
Calrissian: Would have loved to have been the colour of chocolate
