Why are gm foods used and what are some advantages?

Genetically modified (GM) foods are used to enhance agricultural productivity, improve resistance to pests and diseases, and increase tolerance to environmental stresses such as drought and salinity. Advantages include higher crop yields, reduced need for chemical pesticides, and the potential for enhanced nutritional content. Additionally, GM foods can help address food security by ensuring a stable food supply in the face of growing global populations. These modifications can also lead to more sustainable farming practices by reducing resource use.
