Many consumers — especially those who consider themselves ‘progressive’ — have come to embrace the hard-edged beliefs, promoted by factions of the organic industry, that gene-altered crops are less safe, nutritious and sustainable than organic crops and foods.
The chief promoter of anti-biotechnology claims is the Organic Consumers Association  led by Ronnie Cummins, with some help from foodies like Michael Pollan  and Mark Bittman . The OCA has campaigned relentlessly against conventional agriculture, but it’s greatest ire is reserved for biotech crops and foods.
The OCA’s home page promotes a litany of anti-science posts—mostly tirades written by Cummins or from well-known anti-biotech advocacy groups, usually with no reputable sources linked. The centerpiece of its current campaign is a guide  titled “GMO Myths and Truths .” If only to ridicule them, OCA lists claims made by prominent scientists and endorsed by every major science organization  of note in the world, including in Europe where politicians, but not scientists, have promoted bans and restrictions.
