In a campaign reminiscent of the  Starbucks rBGH campaign, (which ultimately culminated not only in a pledge by the java giant not to sell dairy from cows treated with rBGH, but also created a domino effect, causing most large retailers to make the same agreement) , Food and Water Watch has initiated a national campaign to pressure Walmart to do the right thing and to live up to their sustainability claims. Just last week, Walmart launched a brand new website called The Green Room to exhibit their green credentials. Over the past couple of years they’ve run public relations campaigns touting their support of local farming, healthier eating, and providing oases in food deserts.

Walmart sells $129 billion worth of food (taking a whopping 25 percent of grocery sales throughout the US, and much more in some areas) each year, making it the most powerful food retailer in the world. If Walmart agreed to not stock GE sweet corn, it is highly likely that other retailers would follow their lead. It would also relieve farmers of the economic pressure to plant the biotech seeds.

If you’re in the know about GMOs, you know there’s a lot we don’t know—and a lot to be wary of.  We don’t know the long term effects of GMOs on humans and  a new study suggests there is reason to worry. The potential environmental risks are many, including the rise of superweeds and resistant pests, the threat to biodiversity and the inevitability of crop contamination.  There are also the ethical and economic concerns associated with patenting of living organisms and the ownership of our food supply by corporations like Monsanto.

Since last fall, Food and Water Watch and their partners at the Center for Environmental Health, Center for Food Safety, CREDO Action, and Food Democracy Now! have been asking consumers to sign a petition saying that they would refuse to buy GE sweet corn and are asking retailers and food processors not to sell it. As of now, that petition has over a quarter million signatures.  Walmart is powerful, but consumers hold the ultimate power: all great social change starts from the bottom. Join the movement today.
