This 1992 FoxSense graphic has often been criticized as being a bit of an overstatement.
For me, the overstatement originates from the enthusiastic marketing, sales, and use of toxic chemicals for a wide variety of reasons and uses, including spraying poisons on our crops (our food) and watersheds (drinking water).
And then, of course there's a global amphibian decline, colony collapse disorder (bees), and biological magnification of toxic chemical concentrations in food chains everywhere (including the Arctic).
For an expanded discussion, please read "The Safe, Non-toxic Garden" essay in the spring 2013 issue of EdibleWastatch.
If you have a choice, which overstatement would you like to base your health on?
