What we eat has changed more in the last 40 years than in the previous 40,000. The survival of the current food system depends upon widespread ignorance of how it really operates.

One might expect that the families of murder victims would be showered with sympathy and support, embraced by their communities. But in reality they are far more likely to feel isolated, fearful, and ashamed, overwhelmed by grief and guilt, angry at the criminal-justice system, and shunned by their old friends.
