PORTLAND – Thousands of protesters took to the streets of Portland Saturday to voice their frustrations with what they call unethical actions by biotechnical company, Monsanto.
Police estimated almost 6,000 marchers showed up at 11 a.m. Among a list of qualms protesters have with the biotech giant is the company's use of patent law to control seed supply.
The protest is one of many under way across the U.S. and in dozens of other countries.
"March Against Monsanto" organizers say they're also calling attention to the dangers posed by genetically modified food and the companies that produce it.
Protests were held in more than 400 cities in 52 countries Saturday.
Genetically modified plants are grown from seeds engineered to resist insecticides and herbicides, add nutritional benefits and improve crop yields. Some believe they can lead to health problems and harm the environment.
Opponents have pushed for mandatory labeling, though the federal government and many scientists say the technology is safe.
Monsanto Co., based in St. Louis, said Saturday that it respects people's rights to express their opinion, but believes its seeds help farmers produce more food, while conserving water and energy.
