Organic Consumers Association

Campaigning for health, justice, sustainability, peace, and democracy


March Against Monsanto. May 23. Everywhere.
It's more critical than ever that we turn out millions of people around the world on May 23 to make it clear to world leaders that it's time to hold Monsanto accountable.
OCA's message this year is simple, but powerful: Monsanto Makes Us Sick.

UPDATE: The OCA is calling on consumers to organize National Days of Action on May 26, 27 or 28 at the district offices of Congress members, asking lawmakers to reject the DARK act (HR 1599)! Learn more here.

Thanks to a great response we are out of materials! 1000 packets will be mailed out across the U.S. and Canada!

You can download and print materials here.
