I had been neglecting the blog due to a new YouTube channel I'm trying to grow. Today, however, a television crew visited the IPK research center where I work, interested in hearing firsthand the scientists' opinions on the ongoing debate about transgenics in Germany and the EU. This inspired me to write this post. Let me be clear from the outset: while personal preferences and concerns are valid, it is also crucial that the public debate on GMOs be based on scientific evidence and consider the global context of food security and agricultural development.
Kenyan plant pathologist Florence Wambugu summarized it pointedly in an interview: It is fine for Europe to debate whether to have GMOs or not, but can we please eat first? Her question puts the urgency of the matter into perspective. Agriculture currently accounts for 50% of all global topsoil loss, 33% of global greenhouse gas emissions, and 80% of deforestation worldwide. In this scenario, biotechnology, and specifically GMOs (Genetically Modified Organisms), offers real hope for reducing agriculture's enormous ecological footprint while producing more and better food.
The intense debate over GMOs appears to be, in many respects, a privilege of those nations that have already achieved food security. Decades of accumulated scientific evidence show that GMOs are not only safe for health and the environment but also directly benefit the farmer by enabling higher yields with less investment in fertilizers, pesticides, and other inputs. Despite this, significant skepticism persists in parts of the public, a phenomenon similar to that observed with other scientific consensuses. The real danger arises when this disconnect from evidence influences the political sphere, leading to regulations that, instead of protecting, can hinder progress and generate negative consequences for society. It is important to remember that the increased life expectancy and food abundance in the modern world are due to scientific and technological advancements, not to methods with less empirical support.
Furthermore, the claim that transgenics pose a particular risk to the environment is not accurate. In fact, one of the essential requirements for the approval of a transgenic crop is to demonstrate that it cannot hybridize with nearby wild relatives—a standard that is not applied with the same rigor to varieties obtained through traditional breeding methods.
The European Union's stance on this issue presents a notable contradiction: it prohibits the cultivation of most transgenics on its territory but simultaneously allows their large-scale importation. Without these imports, primarily of soy for animal feed, it would be impossible to sustain the livestock industry and, consequently, the supply of meat and derivative products to the market. A total ban on imports would trigger a supply crisis and a price surge that would directly impact consumers.
In practice, the technical and scientific debate on GMOs was settled long ago. The widespread rejection in some regions seems more an ideological stance than a precaution based on science. For a broader perspective, one need only look at the difficulties faced by farmers in places like Sri Lanka or Mexico, where the adoption of less productive agricultural models, promoted under false premises, has had very serious consequences.
