In this blog post, I will summarize the background and current state of the GMO industry, its pros and cons, and how our society should respond.

What Is the GMO Industry and Why Is It Important?

GMO stands for Genetically Modified Organism, referring to organisms created by inserting or removing specific genes using genetic engineering technology. South Korea’s food safety laws also define foods manufactured or processed using genetic recombination technology as GMOs. As demands to address food and energy issues and climate change have grown, companies possessing genetically modified seeds and the agricultural production technologies that utilize them have emerged, and the GMO industry has grown rapidly.
At one point, the GM seed market was valued at approximately $13.2 billion, accounting for a significant portion of the total seed market. The value of final products derived from these seeds ranges from tens of billions to hundreds of billions of dollars, and the industry has reportedly maintained a high annual growth rate. Since South Korea has a very low self-sufficiency rate for major food crops (excluding rice) and is highly dependent on imports, GMO technology and the related industry hold significant importance in terms of food security.

Key Advantages of GMO Technology

The primary advantages of GMO technology include the potential to enhance nutritional value and enable high-quality mass production. Research is underway to increase specific nutrients or alter fatty acid composition to produce high-quality vegetable oils by inserting genes for specific purposes or removing unnecessary genes (e.g., using Agrobacterium, gene guns, and protoplast fusion).
In addition, active research is underway to develop varieties resistant to environmental stresses such as pests, diseases, herbicides, and drought, enabling stable production even in poor soil conditions. The commercial adoption of herbicide-resistant crops (such as Roundup Ready), pest-resistant varieties (such as Bollgard), and drought-tolerant varieties (such as Drought-tolerant hybrids) has contributed to increased productivity on smaller land areas. Such technological advances play a crucial role in enhancing the efficiency of food production.

Major Concerns Regarding GMOs

Opponents of GMOs express concern that their long-term safety for humans and livestock has not been sufficiently verified. Claims have been raised that some animal studies reported weakened immune systems or allergic reactions, and international organizations have also recommended a cautious approach to these issues.
From an environmental perspective, issues such as genetic contamination resulting from gene flow, the emergence of superweeds or superpests, and increased environmental pollution due to the overuse of specific herbicides and pesticides have been raised. In particular, there are concerns that widespread cultivation of a single variety could reduce biodiversity, making crops more vulnerable to extreme weather events or new pests and diseases.
Economic and social concerns include the potential for patents on GMO technology and seeds, as well as the possibility of market domination by multinational corporations. Patent-based technology royalties increase seed costs, placing a burden on farmers and potentially leading to issues of food sovereignty.

Examining Key Issues and Real-World Cases

A review of GMO-related incidents reveals that, in some cases, problems stemmed from poor management of distribution and manufacturing processes rather than the GMOs themselves. For example, the tryptophan incident of the 1990s was found to be caused by impurities introduced during the manufacturing process, rather than an inherent flaw in the genetically engineered product itself. While this incident sparked safety debates, investigations revealed that issues with manufacturing processes and quality control were at the core of the problem.
At the same time, decades of research and numerous independent reviews have often concluded that “genetic modification itself” is not inherently dangerous. However, this does not mean that all GMOs are unconditionally safe; rather, it means that individual and rigorous safety assessments and management for each product and process are essential. Therefore, the safety of GMOs depends on scientific verification and the thoroughness of the regulatory system.
Another point of contention is the criticism that technological advancement is unnatural for humans. However, since the dawn of agriculture, crop improvement and selective breeding have been ongoing processes; even maize evolved into its current form through human selection and breeding from its wild ancestor, teosinte. While the emergence of new technologies creates new risks, research and development to address them are also proceeding in parallel.

Policy and Social Considerations and Conclusions

GMOs have the potential to increase food production, but increased production does not directly translate to solving the problem of hunger. The Food and Agriculture Organization (FAO) and the World Food Programme (WFP) have emphasized the importance of distribution, political, and social factors alongside food shortages. Any technology must be properly implemented within its social context to yield tangible results.
In the case of South Korea, since GMO raw materials are imported from the United States, Brazil, Argentina, and other countries, the country is sensitive to international supply chains, regulations, and price fluctuations. Along with government research and support, transparent distribution management, strict safety assessments, clear labeling systems, and communication with consumers are necessary. Given the technology-intensive nature of the industry, investment in research and development remains essential; however, policy mechanisms to protect the market and farmers must also be established.
Ultimately, the GMO issue is not solely a matter of science. Only when scientific verification, regulation, corporate responsibility, farmers’ rights, consumers’ right to know, and political and cultural acceptance all come together can the industry develop in a safe and desirable direction. Therefore, when considering the GMO industry, we must evaluate its technical pros and cons in a balanced manner and maximize benefits while minimizing risks through oversight and social consensus throughout the entire process.
