Hello All, I found this interesting article when helping my son find news articles on pollution. The title of the article is: Scientist Uses Tombstones to Track Environmental Changes http://news.nationalgeographic.com/news/2001/11/1126_tombstonecopy.html If you ever wondered why some cemeteries are in pretty good shape for their age and others are not, this may be your answer. (besides neglect, which we all know happens).
