Lori Timbol, organizer of Saturday's anti-GMO rally in Kelowna, uses a bullhorn to lead marchers along Harvey Avenue near Cooper Road.
They wore haz-mat suits, gas masks and Grim Reaper masks to show they feel genetically modified foods are poison and eventually lead to health problems and death.
"We're here to fight GMOs," said a well-versed Sidney Fudger, 12. "We want the right to eat foods from natural seeds."
Most of the other protesters at the March Against Monsanto in Kelowna Saturday were cloaked in red - the colour for stop.
"We asked people to come out dressed in red because we want Monsanto to stop forcing genetically modified seeds and foods on the world," said Lori Timbol, the organizer of the March Against Monsanto locally.
"Monsanto is poisoning us."
Giant U.S.-based multinational seed company Monsanto has become the target of worldwide protest for developing genetically modified seeds for farmers to produce food for humans and feed crops for livestock.
On Saturday, similar March Against Monsanto events were held in more than 400 communities around the world.
An estimated 70 per cent of the foods we eat are GMO (genetically modified organisms).
For instance, GMO corn is eaten by humans and GMO corn is fed to cows that supply our dairy and meat, and bees cross-pollinate from a GMO plant to another plant, making it GMO.
"Fifty other countries around the world either require GMO foods to be labelled as such or have banned GMO foods. Mexico just banned GMO corn the other day," pointed out Timbol.
"Yet in Canada, labelling isn't required and GMOs are in at least 70 per cent of our foods."
Timbol wants to see at least labelling in Canada, and ideally an outright ban on GMO foods.
"We need to do this to keep ourselves and our children safe," she said.
GMO foods come from seeds and plants that have been genetically engineered for faster growth or resistance to disease.
However, protesters believe GMOs are also toxic and can contribute to everything from gastrointestinal problems, thyroid issues and infertility to cancer, Parkinson's disease and Alzheimer's.
About 300 people came out to the Kelowna march.
The crowd gathered at the Parkinson Recreation Centre parking lot, dressed in red and waving placards.
They then marched east along Highway 97 to honking cars to the Kelowna Farmers' and Crafters' Market and back again.
"We want to show our support for local farmers and non-GMO foods," said Timbol.
