What are genetically modified organisms (GMOs) used for in agriculture?

Genetically modified organisms (GMOs) are primarily used in agriculture to improve food production traits through the alteration of an organism's genetic material. This modification can result in various benefits such as increased resistance to pests, enhanced nutritional content, improved yield, and better tolerance to environmental stresses like drought or salinity. By inserting specific genes into a plant's DNA, scientists can impart desired traits that can help increase overall efficiency and productivity in farming.

For example, crops might be engineered to be resistant to certain pests, which leads to reduced reliance on chemical pesticides and can thus benefit both the environment and the farmers’ bottom line. This approach enables farmers to produce more food on the same amount of land, thus addressing food security concerns in a sustainable manner.

Regarding the other options, preserving traditional farming methods does not reflect the purpose of GMOs, as they represent a significant departure from conventional practices. GMOs can enhance the visual appeal of crops, but it is not their primary use; rather, the focus is on functional traits that contribute to food quality and agricultural efficiency. Lastly, while GMOs may streamline certain management practices, they do not eliminate the need for overall agricultural management, which is essential for maintaining plant health and farm sustainability.
