Latitude error[edit]

In the statement "the need to better utilize the sun's UV radiation with decreasing latitude", shouldn't that be "increasing latitude"? There is less UV radiation available for Vitamin D production at 80 degrees latitude (above the Arctic Circle) than at 10 degrees latitude, and so there is less need for pigments to block UV. "Increasing latitude" = "decreasing UV radiation". Chris the speller (talk) 15:27, 30 July 2009 (UTC)[reply]

Yes, it does seem like the correction you suggest is right. http://www.nas.nasa.gov/About/Education/Ozone/radiation.html Shyamal (talk) 11:16, 31 July 2009 (UTC)[reply]
