I am more willing to believe that our diets (like a pp mentioned) have more to do w/the rising skin cancer rates and our body's inability to handle the sun, than the theory that the sun is bad.
I just can't fig out why humans would be put on the earth w/sun, have to work and live in sun exposure when it would be so bad for us. What did people do thousands of yrs ago?
You mean back when there weren't huge holes in the ozone layer caused by CFCs?
Well, if they lived somewhere very sunny, they evolved dark skin as protection. That's not much use to people of Irish extraction who are now living in Australia.
