Genetic modification in agriculture is like nuclear power: nobody loves it, but climate change has made it an important option.
Alenkinab [10]

The correct answer is option c, that is, people voting not to allow government money to fund genetic modification research.  

The scientists from the Food and Drug Administration had continuously warned that the genetically modified foods can develop hard to detect and unpredictable side effects, like toxins, allergies, nutritional issues, and new diseases.  

The GM plants, like corn, soybean, canola, and cottonseed, have had foreign genes forced into their DNA. The inserted genes come from species, like viruses and bacteria that have never been in the supply of human food.  

The genetic engineering procedure develops massive collateral destruction, making mutations in several locations all through the DNA of the plant. The natural genes can be permanently turned off or deleted, and many may have modified their behavior.  

Even the gene inserted may get rearranged or damaged, and may produce proteins, which can promote disease or initiate allergies.
