Agricultural biotechnology plays a significant role in achieving food security primarily through the improvement of crop yield and resistance to pests. By utilizing biotechnological methods such as genetic modification, scientists can develop crops that are not only more productive but also better equipped to withstand environmental stressors, diseases, and pests.

When crops have enhanced resistance to pests, they require fewer chemical pesticides, which can be beneficial for both the environment and farmer costs. Furthermore, increased crop yields mean that more food is produced on the same amount of land, thus helping to meet the food demands of a growing population. This approach also contributes to sustainability in agriculture by optimizing resource use and reducing the need for land expansion.

In contrast, while the number of genetically modified foods can play a role in food diversity, focusing on enhancing crop yield and pest resistance directly addresses the core issues related to food security. Similarly, while aspects like reducing food processing times and enhancing flavor might improve the consumer experience, they do not directly contribute to the fundamental goal of ensuring sufficient food production to meet global needs. Thus, improving crop yield and pest resistance stands out as a critical strategy in the context of food security.
