The Dirty Truth About ‘Organic’ Produce
Passionate advocates of organic farming and foods resemble members of a religious cult, one founded on a «back to Nature» mentality. They are not so fundamentalist, however, that they do not make concessions to reality.

The decisions are made in a murky process that combines agronomy, lobbying and fundamentalism.
