Carcinogens are highly represented by the ingredients of vegetables theirselves and trace amounts are only found in pesticide sprays. Dr Ames (who the Ames test is named after) says that media blows things out of proportion. WAY OUT. It is said by reputable sources that media is scientifically and economical idiots and should only be good for reporting the days events as facts...Scientists today (though of course not the ones that don't agree with media buzz or help to sell add space/time/papers) agree that a lot of the hype over going organic was the presses fault for trying to run with stories that were simply not true or used statistics and 'facts' from other media sources and that involves a 'circular' dependancy on unreliable sources. In fact, the governments idea of being organic is not really organic at all...why not support 'local' for the obvious reasons and let your garden grow using 'chemicals' in their proper proportions that have been formulated. lab tested, and time proven to help your garden grow?
