The global day of protest against the giant corporation Monsanto was a major success. On Saturday, demonstrators took to the streets in more than 50 countries for a “March Against Monsanto.”

The protests were aimed at highlighting Monsanto’s destructive business practices, like the making of genetically-modified seeds. Demonstrators in the U.S. called for the labeling of genetically-modified organisms. Protest organizers say that genetically-modified food can lead to cancer and birth defects.

The Facebook call for protests against the corporation sparked massive demonstrations that saw about two million people show up. Raw Story notes about 436 cities witnessed Monsanto protests.

“It was empowering and inspiring to see so many people, from different walks of life, put aside their differences and come together today,” Tami Canal, the Utah-based activist who organized the campaign, told the Chicago Sun-Times. “We will continue until Monsanto complies with consumer demand. They are poisoning our children, poisoning our planet. If we don’t act, who’s going to?”

AlterNet’s April Short recently highlighted five of the most horrifying business practices Monsanto has engaged in. Those include the making of toxic chemicals like Agent Orange for the U.S. military, which killed and maimed hundreds of thousands of Vietnamese, and pesticides that have been linked to diseases.

Short also noted that Monsanto has become a monopoly in the U.S. that has contributed to putting farmers out of work.
