Media scare campaigns will one day stop us utilising a vital piece of new technology.
BPA a chemical that is used in some plastics and has never been shown to have any negative impact on human health is currently being removed from plastic food containers. Someone claimed it was bad so "BPA FREE" stickers started appearing on containers as a selling point. I've even seen them on aluminium drink bottles. I don't know how aluminium could have BPA in it in the first place? Now a similar controversy has erupted regarding nano-particles of zinc oxide in sun screen. This is another unsubstantiated claim of bad health effects. You would think that in a country with such a high rate of UV induced skin cancer as AUS, some caution should preceed any claim that sunscreen is bad for you, but the media seem unable to resist a bandwagon.
