The protesters say Salt Lake City is aligning with a reported 395 cities worldwide to protest the company.
“There definitely needs to be a lot of awareness especially among the members of Congress,” said Terry Nelson.
Protesters are not only taking a stand against Monsanto, but against lawmakers who pass laws to protect the company.
They say the President and Congress collectively passed what is nicknamed the “Monsanto Protection Act”. It bans courts from halting the sale of Monsanto’s genetically-modified seeds.
“We're trying to change that, we've got to repeal a vote coming up in the Senate,” said Donald Schaffer who is marching against Monsanto.
Protesters in Salt Lake City marched and held signs to show their support against Monsanto.
One woman even used her infant to protest. She wrote on its shirt, “Protect me from Monsanto.”
“I'm so glad there are so many people here getting the word out making sure everybody knows what's really happening,” said protester Brian Looney.
Protesters say they want transparency. They want genetically modified foods to be labeled. They also want lawmakers to question the source of food.
“Regardless of religion race gender everything; people are coming together all around the world for this,”said Schaffer.
ABC 4 Utah called Monsanto’s media relations phone number and left an email. There was no response before this online story was posted.
