Final answer:
Scientists defend genetically modified food by highlighting its benefits in improving agricultural yield, enhancing nutritional content, and promoting environmental sustainability.
Step-by-step explanation:
The main defense of genetically modified food by scientists is improving agricultural yield and efficiency, enhancing nutritional content, and promoting environmental sustainability.
Scientists argue that genetically modified crops can produce higher yields, which can help address global food security challenges. They also emphasize the potential to enhance the nutritional content of food crops, such as increasing vitamin or mineral content.
Furthermore, genetic modification can contribute to environmental sustainability by creating crops that are resistant to pests without the need for excessive pesticide use.
