Study Notes
Genetic Modification in Corn Production
- In 2015, 89% of corn grown in the United States came from genetically modified seed varieties.
- Genetic modification technologies led to a decrease in insecticide use as genetically engineered crops became more widespread.
- Conversely, the increased use of genetically engineered crops resulted in a rise in herbicide use.
Safety of Genetically Modified Crops
- Multiple science organizations, including the World Health Organization, deem genetically modified crops safe for human consumption.
- Despite scientific evidence supporting the safety of GM foods, many consumers remain skeptical and believe non-GM foods are healthier.
Learn about the impact of genetically modified crops on agriculture, including their effects on pesticide use and safety for consumption.
