Why are genetically modified organisms so controversial?

Genetically modified organisms (GMOs) are controversial primarily due to concerns about their potential impact on human health, the environment, and biodiversity. Critics argue that GMOs may lead to unintended consequences, such as the development of pesticide-resistant pests or the loss of traditional crop varieties. Additionally, ethical considerations around food labeling and corporate control of the food supply contribute to public apprehension. Supporters, however, point to the potential benefits of GMOs, including increased yields and reduced pesticide use.
