Whether it is Bt cotton from India or Bt corn from the United States, ultimately, they cannot bypass the two core points of whether regulation is in place and whether resistance is controlled. In India, the refuge zone system is largely unestablished, and resistance spreads like it is left unchecked, eventually greatly reducing the effectiveness of crops (Tabashnik and Carriere, 2019). Although the United States started early and implemented the refuge zone system well, it now also has to face the situation where resistance is emerging at an accelerated pace. An obvious revelation is that technology alone is far from enough. Regulatory strategies must keep up, and even stay ahead. In the future, if Bt crops are to continue to play a role, a more flexible regulatory system must be established. It should not only rely on scientific data but also be down-to-earth, taking into account the agricultural realities and socio-economic conditions of different countries and regions. 6 Challenges and Public Concerns in Regulation and Risk Assessment 6.1 Agricultural biodiversity protection and long-term ecological effects Disputes over the ecological impact of Bt crops have never ceased. Even though it can reduce the use of chemical pesticides and seems to be a benefit for biodiversity, many problems cannot be so simply concluded. Whether non-target organisms are affected, whether soil systems are disrupted, and whether genes will leak into wild populations? In recent years, research has also pointed out many blind spots. For instance, the assessment of changes in soil organisms and the range of gene mobility is obviously not detailed enough (Koch et al., 2015; Then et al., 2022). Moreover, in some developing countries, merely establishing a regulatory framework is already a challenging task, let alone tracking ecological impacts over the long term. Although many countries have written in their documents that they will conduct environmental monitoring and comparative assessment, when it comes to actual implementation, it is often discounted due to the lack of personnel, equipment and experience. 6.2 Monitoring and management strategies for resistance development The issue of resistance, to be honest, is no longer new, but for Bt crops, it might be the most realistic and intractable challenge. The insect-resistant genes worked quite well in the first few years of use, but as time went by, the pests gradually began to "adapt". To delay this process, many countries have promoted resistance management strategies, such as refuge cultivation, regular monitoring of pest changes, and rapid response once problems are detected (Carriere et al., 2019; Gupta and Matharani, 2025). But it cannot be strictly enforced everywhere. In some regions, supervision is not strict enough, and in some places, no one is involved at all. As a result, the issue of resistance is treated as an "expected" matter and left unchecked. In fact, from the perspective of ecosystems and agricultural practices, scientific data is only the foundation. What is more crucial is for the government, farmers, and research institutions to join forces and treat this matter as a regular task rather than a temporary remedy. 6.3 Social ethics, public perception, and the need for transparent information disclosure The technology of genetic modification itself is not wrong, but once it comes to sensitive points such as "food" and "environment", the public's attitude is often not as rational as just looking at data. In many countries, the suspicion towards Bt crops is not due to poor technology, but rather the lack of transparency in information disclosure, unclear publicity, and the frequent politicization of approval procedures. For instance, in China and India, the advancement of genetically modified projects has not been smooth sailing. A large part of the reason for this is public distrust (Prasad and Thakur, 2025). To change this situation, it is not enough to rely solely on experts' persuasion, but rather to ensure that scientific data, risk assessment and decision-making processes are truly visible and understood. Giving farmers, consumers and policymakers the opportunity to speak not only eliminates misunderstandings but also makes it easier to find a balance between social values and technological development. Ultimately, science communication is not about making everyone "accept" it, but about making everyone "understand" it. This is the foundation for the regulatory system to go further (Qaim, 2020).
