HOWARD LOVY: Nanotech In Sunscreen: What’s The Harm? “For more than a decade now, anti-technology organizations such as the ETC Group and Friends of the Earth have been warning against the possible hazards of nanoscale titanium dioxide and zinc oxide in sunscreen. This warning has come with absolutely no scientific proof. They made it up.”

That seems to be the pattern. And as Lovy notes, lazy journalists — that is, nearly all journalists — tend to repeat such environmental warnings as if they had some scientific basis.
