Why genetically modified foods are harmful?

Genetically modified (GM) foods can pose potential risks, including environmental concerns such as biodiversity loss and the development of resistant pests and weeds. There are also health concerns regarding allergenic reactions or unintended effects on human health, which may not be fully understood. Additionally, the consolidation of seed patents among a few corporations could undermine food sovereignty and farmer independence. These factors contribute to the ongoing debate about the safety and ethics of GM foods.
