As per the last post, this is courtesy of GrassrootsHealth. The particular presentation I'm highlighting is Skin Cancer / Sunscreen -- the Dilema, by Edward D. Gorham, Ph.D., Frank C. Garland, Ph.D., Cedric F. Garland, Dr.P.H. and Sharif B. Mohr, M.P.H. Let's jump right in with some graphical highlights. Melanoma has been getting worse and worse, where? Indonesia? Brazil? Cuba? How about Tunisia -- all places pretty close to the equator where the sun is powerful all the year long. Bzzzzt. Norway. In fact, the father north you go in the northern hemisphere, or the father south you go in the southern, skin cancer rates go up. Oh, well that's because of the ozone, right. Bzzzzt. Wrong again. Looks like ozone thickness is higher at extreme latitudes. The sunscreen manufacturers are doing just fine. Really, really fine. The more money they make, the more melanoma, and the more calls go out to use more sunscreen. Excellent business plan.
