Final answer:
The use of biotechnological approaches for crop improvement is more controversial than their use in preparing medically useful products due to concerns about safety, ethical considerations, and monopolization. Cheaper and more manageable production is seen as a potential benefit of biotechnology.
Step-by-step explanation:
The use of biotechnological approaches for crop improvement has been more controversial than their use in preparing medically useful products due to several reasons. These reasons include concerns about the safety and potential environmental impacts of genetically modified organisms (GMOs), ethical considerations related to manipulating the genetic makeup of plants, and concerns about the monopolization of the seed industry by large biotech companies. However, one reason that is not commonly cited for the controversy is the cheaper and more manageable production that biotechnology offers, which is actually seen as a potential benefit.
