Kevin highlights the real problem with genetically modified (GM) food. It's not that it might be poisonous to our bodies, but that it is toxic to our body politic.
Dana offers a a case study in scientific integrity. Though this is his first foray into the Guardian, I've read quite a bit of Dana's writing and he knows what he's talking about (he's also now posted a further analysis of the replies to his Guardian piece).

Infant mortality and the suicide rate fell, and spending on entertainment was one of the few areas that grew."See also this piece by Caroline Lucas MP.
