Are GMOs Good or Bad? Genetic Engineering & Our Food
Kurzgesagt – In a Nutshell・2 minutes read
Genetic engineering is a controversial topic, especially in food and agriculture, due to concerns about GMOs, even though it allows for precise trait selection in plants unlike traditional methods like selective breeding. Despite criticisms, GMOs have shown positive impacts in agriculture, like reducing pesticide use and saving crops from diseases, suggesting potential benefits for environmental sustainability.
Insights
- Genetic engineering enables precise selection of desired traits in plants, differing from the gradual, luck-based process of selective breeding used historically.
- Despite concerns about GMOs, their positive impacts, like reducing pesticide use and saving crops from viruses, suggest a potential for improving agriculture and environmental sustainability.

Recent questions
What is genetic engineering?
Genetic engineering is a process that involves manipulating an organism's DNA to create desired traits or characteristics.
How do humans genetically modify plants and animals?
Humans have been genetically modifying plants and animals for thousands of years through selective breeding, which involves choosing organisms with desired traits to reproduce and gradually enhancing those traits over generations.
What are concerns about GMOs?
Concerns about GMOs include gene flow between genetically modified and traditional crops, unintentional spreading of engineered DNA, and potential impacts on human health.
What are the benefits of genetic engineering in agriculture?
Genetic engineering allows for precise selection of desired traits in plants, such as making them larger or pest-resistant, unlike the luck-based process of selective breeding.
How have GMOs positively impacted agriculture?
Despite criticisms, GMOs have shown positive impacts, such as reducing pesticide use in crops like eggplants and saving the papaya industry in Hawaii from a devastating virus, indicating the technology's potential for improving agriculture and environmental sustainability.
