Hundreds of thousands across the US joined the worldwide rally against biotech giant Monsanto and genetically engineered crops. It comes shortly after the Senate turned down a bill that would allow states to require the labeling of GM foods.

Organizers of the major rally that swept through dozens of nations around the globe on Saturday, urge a repeal of the so-called Monsanto Protection Act, and call for a boycott of Monsanto products.

Participants in the March Against Monsanto were also demanding the right to know what they’re paying for and what their children eat. The protesters called for labeling of GM foods, which they say could pose a danger to human health, and demand further scientific research of such products.

RT covers the protest which is getting a mainstream media blackout, with RT's Anastasia Churkina - who as at the heart of the protest march in New York City – one of dozens of American cities that are staging protests against Monsanto.

“According to our estimates there are over 2,000 here,” she said. “All these people have gathered here today to speak out against this giant biotech corporation that for years has been accused of manipulating and corrupting farmers throughout the world and monopolizing the agriculture industry.”

In Washington DC, a crowd of marchers gathered in front of the White House waving banners and posters.

Meanwhile, the US-based seed giant maintains that its seeds improve agriculture since it helps farmers to produce more from their land while saving resources such as water and energy. At the same time, Monsanto said on Saturday, they respect people’s rights to express their opinion on the matter, AP reported.

Hundreds of protesters took to the street in Los Angeles and marched towards the City Hall carrying signs with messages such as “Label GMOs, it’s our right to know” and “Real Food 4 Real People.” Rallies and colorful events were taking place all across the city until 5 pm.
